Windows 10 calculatore
Hi all, Today when using the calculator app in Windows 10 I noticed that NVDA doesn't read the keys I pressed (backspace, clear, etc) and the changes make to the output display, for example if I delete a number NVDA won't announce the change, even with the latest version of Windows 10 Essentials add on installed. If I'm correct, I started noticing this bug since I upgraded to 2016.3 RC1. Is this a bug with NVDA? Or the Windows 10 Essentials add on...


Hi, Does this happen if NVDA is run in Core mode (all addons disabled)? Cheers, Joseph

Haven't try that, maybe I'll try it some point.


Hi, I tried installing a new copy of NVDA 2016.3 RC1, updated to 2016.3 RC2, in a new Windows 10 virtual machine, and tested the calculator app, and the keys were being read out just fine, both with and without the Windows 10 essentials add on. Now I wonder why NVDA did not read the keys being pressed when I tried it on my Surface 3 earlier in the day...


For anyone who doesn't happen to care for the Windows 10 Calculator App, there is also the option of going back to good, oldfashioned Calculator Plus that you've known and loved since the WinXP days. That's what I did since it's still supported and I just like the way it behaves and looks much better than the new one. There's no need to uninstall the Win10 Calculator App, either. I ended up putting a shortcut to Calculator Plus on the Quick Launch bar for easy access. I worry a lot. . . I worry that no matter how cynical you become it's never enough to keep up. ~ Trudy, in Jane Wagner's "Search for Signs of Intelligent Life in the Universe"


How well does it work with NVDA? Also does it support scientific calculations (logs, sin, cos, etc)?


Hi, Calculator+ is inaccessible with NVDA for two important reasons: · Same executable name as modern Calculator, which means it is difficult to write a separate app module for this one. · It is hard to find out the exact label for most buttons in there due to the way it exposes information to NVDA.

Jo.seph, I am not talking about the Calculator Plus that's available through the Store. That's a thing of its own. The Calculator Plus that I linked to is an old Windows application that has been around since dirt and doesn't use the new universal interface. If it's not accessible to NVDA, just based upon its appearance, that would be very odd. It looks exactly like the calculator that I used from WinXP up through Windows 7. I just want to make certain that we're talking about the same Calculator Plus here. This one has three separate views: Standard, Scientific, and Conversion. I stick to the Classic View without digit grouping (that is, there are no commas in the numbers to the left of the decimal point). I worry a lot. . .

Hi, So we might be talking about two different beasts then (my apologies). Cheers, Joseph

Yes it works very well with NVDA. It has Standard, Scientific, Programmer and Date calculators plus a host of Converter interfaces. There is a comprehensive list of shortcut key codes on the MS web site covering the functions you specified.

A satisfactory alternative calculator is Google itself. I wrote the below material overten years ago before I hadever heard of NVDA. So, the material below references JAWS. Sorry! I never published any of this material. Chapter 24: Google As Calculator And Conversion Tool
By Michael R. Cross M. S. Mathematics
Most people only use Google to hunt for information and links to interesting sites, but they are missing some of its most powerful features. Google has many uses which don’t send you on a hunt through a long list of web sites. It is truly a manyfaceted reference tool.
24.1 Calculations
Sooner or later, everyone needs a calculator if only for a short calculation and occasionally, for a longer one. The Start Menu contains a calculator under “Programs” (Windows 2000) and under “All Programs” (Windows XP. However, it only permits you to perform one arithmetic operation at a time. It would be nice to type more complicated expressions such as (87.2 +17283/7)*(21 3/17). So, you might prefer to use something else. There is good news! You can use Google’s “Search edit:” box to evaluate such expressions.
24.1.1 Addition, Subtraction, Multiplication, Division, and Exponents
Addition, subtraction, multiplication, and division are represented respectively by ‘+’, ‘‘, ‘*’, and ‘/’. Mathematics texts denote exponents by superscripted numbers, however, Google expects you to put a carrot in front of an exponent. A carrot is the symbol ‘^’. An example would be “3^2” which means 3 squared.
24.1.2 Functions Recognized by Google Search
Google search recognizes several functions such as the square root function, the logarithm function (both common and natural) and their inverses, the trigonometric function and their inverses, and modulo arithmetic. You can include these functions in an expression you want Google to evaluate. It also recognizes some operators such as “% of”.
24.1.2.1 Square Root
One function that occurs frequently in calculations is the square root function. It is designated by “sqrt” followed by the number whose square root is being computed. The function name “sqrt” and the number are enclosed in parentheses “()”. An example would be “(sqrt 64)” which means “the square root of 64”. Example: Take the square root of 64, add 1 to the result, and then raise that to the exponent 3. To do this, put focus on the “Google Search edit:” box on the Google web site. When the browser connects to the Google web site, focus will usually be on the “Search edit:” box. Press the ENTER key to turn on forms mode. Now you can type the expression. You should type “(1 + (sqrt 64))^3”. Next press NumPad + to exit forms mode and tab once to the “Search” button. Ordinarily pressing the SPACEBAR starts a search, but in this case, it causes Google to perform the calculation. The name of the current web page after you pressed the SPACEBAR is “(1 + (sqrt 64))^3 Google Search”, the mathematical expression being evaluated. Verify it with the JFW keystroke command INSERT+T. If the title bar isn’t the expression you want evaluated, there is something wrong with the expression as you typed it. It might be only a typing error. However, if the title bar is the expression you typed, then you got an answer. If you arrow down, you will find the following twelve lines, and you will find your answer in the ninth one down. The eleventh line down is a link that invites you to learn more about calculator.
“ Advanced Search Preferences
Web
Table with 3 columns and 2 rows
(1 + sqrt(64))^3 = 729
More about calculator. table end”
Note that rather than writing “(sqrt 64)”, you can write “sqrt(64)”. Google still understands your intent and calculates the correct result 729. A scientist or mathematician would have probably written it this way. In this example, I showed twelve lines of the result, but in future examples, I will only show the answer. Example: Determine the return on an initial investment of $50,000 at 6% over 30 years. In the Google “Search edit:” box, type “50000*(1.06^30)”. Tab once to the “Search” button and press the SPACEBAR. The title of the web page containing your answer is “50000*(1.06^30)”. Your answer on the result page is the following line. “50 000 * (1.06^30) = 287 174.559” The above expression you typed is a geometric progression (remember high school algebra). Each year, 6% gets added to the original 100% giving 106%. That’s where you get the 1.06. For each of the 30 years, the amount gets multiplied (or grows) by 1.06 (106%), thus the exponent 30. If you put a dollar sign or a comma in the “Search edit:” box, you won’t get an answer.
24.1.2.2 Common And Natural Logarithms
The common logarithm of a number x (denoted by log(x)) is that number which when 10 is raised to that number produces x. That is, 10^(log(x)) = x. Raising 10 to an exponent is the inverse of the common logarithm function. You may think of inverse functions as doing the reverse of each other. Specifically, the Inverse function of the function log(x) is the function 10^x. Verify to yourself that these functions really are inverses. FACT: log(1) = 0 and 10^0 = 1. See if Google gets it right. Google also recognizes the natural log function. Denoted by ln(x), the natural log of x is similar to the common logarithm of x, except the base is not 10 as in common logarithms. It is 2.71828183 and is designated by the letter e. Similar to the common logarithm, its inverse function is e^x. NOTE: You might be wondering why would anyone be interested in such strange functions as ln(x) and e^x. Both these functions have some unusual properties that mathematicians and engineers find useful. Suppose a little cartoon character is on skis riding the curves (graphs) of each of these functions one at a time. For each point (x,y) on the curve ln(x), as he reaches the point (x,y) the slope of his skis is 1/x. When he is on the curve e^x, for each of its points (x,y) as he reaches it, his skis will have slope y. His skis lie inside the tangent line to the curve at the point (x,y). I invite you to use google to get a feel for the relationship between these two functions. Find ln(10) and then raise e to whatever result you got from the previous calculation. You should find that ln(10) = 2.30258509. Does e^2.30258509 equal 10? See if the above result is consistent with the definition of natural logarithm I just stated. Here’s the query and the result. e^2.30258509  Google Search e^2.30258509 = 9.99999997 Well! The result is almost 10, close enough anyway. Let’s find out the value of e. here are the query and the result. Search edit: e^1 Search e^1 = 2.71828183
24.1.2.3 Trigonometric And Inverse Trigonometric Functions
Google also recognizes the trigonometric functions and the inverse trigonometric functions. Angles are in radians. In the definitions below, sideadjacent is the length of the leg of the right triangle bordering the angle in question. Sideopposite is the length of the other leg of the triangle. Hypotenuse is the length of the longest side of the triangle, which incidentally is the side opposite the right angle. The functions are: Sin(angle) sine of an angle = sideopposite/hypotenuse Cos(angle) cosine of an angle = sideadjacent/hypotenuse, Tan(angle) tangent of an angle = sideopposite/sideadjacent, Sec(angle) secant of an angle = hypotenuse/sideadjacent, Csc(angle) cosecant of an angle = hypotenuse/sideopposite, and Cot(angle) cotangent of an angle = sideadjacent/sideopposite. Google also supports the inverse trigonometric functions. They are: Arcsin(sideopposite/hypotenuse) = angle , Arccos(sideadjacent/ hypotenuse) = angle, Arctan(sideopposite/sideadjacent) = angle, Arcsec(hypotenuse/sideadjacent) = angle, Arccsc(hypotenuse/sideopposite) = angle, and Arccot(sideadjacent/sideopposite) = angle. Revisiting an earlier explanation, two functions are inverses means that the inputs (abscissas) of the first function are the outputs (ordinates) of the second function, and that the outputs (ordinates) of the first function are the inputs (abscissas) of the second function. You might say that each function reverses the other. For example, if there is an angle between the hypotenuse and the side adjacent to it, then Arcsin(sin(angle)) = angle. Also sin(arcsin(sideopposite/hypotenuse)) = sideopposite/hypotenuse. When using trigonometric functions, “sin( 30 degrees)” is correct for angle 30 degrees whereas “sin(30)” returns the sine of 30 radians. If you typed “sin(30 degrees)” into the “Search edit” box and activated the “search” button, you would get the following result: sine(30 degrees) = 0.5
24.1.3 Modulo Arithmetic
In elementary school when you were learning long division, before you learned to produce quotients with a decimal point, you expressed the quotient as a number followed by a capital R and a remainder. The modulo operator % produces a remainder. The % is preceded by the dividend and followed by the divisor, and its resulting value is the remainder in that long division problem. In the “Search edit:” box type 27%5, and then activate the “Search” button. The result should be: “27 modulo 5 = 2”
24.1.4 The % Of Operator
This operator is preceded by one number and followed by a second. To state the obvious, it returns the percentage of the second number specified by the first number. As an example, find 7 percent of 89. In the “search edit:” box, type “7 % of 89”. Then activate the “Search” button the result should be: “7% of 89 = 6.23”
24.1.5 Complex Numbers
Google can work with complex numbers too. The numbers that you have seen up to now are called real numbers. A complex number consists of two parts – a real number plus an imaginary part. The imaginary part is a real number times the imaginary number I which is the square root of –1. For instance, if in the “Search edit:” box, you type “sqrt(1)” and activate the “Search” button, the answer is “i”, the imaginary number. The four operations addition, subtraction, multiplication, and division are slightly different than those between real numbers. Suppose that a, b, c, and d are real numbers. Here are the definitions.
24.1.5.1 Complex Addition
(a +b i) + (c +d i) = (a + c) + (b + d)i. Try the calculation (1 + 10i) + (2 + 20i). The result should be: (1 + (10 * i)) + (2 + (20 * i)) = 3 + 30 i.
24.1.5.2 Complex Subtraction
Definition: (a + b i)  (c + d i) = (a – c) + (b – d)i. Try the calculation (1 + 10i) – (3 + 30i). Your result should be: (1 + (10 * i))  (3 + (30 * i)) = 2  20 I
24.1.5.3 Complex Multiplication
Definition: (a + b i) * (c + d i) = (a*c –b*d) + (a*d + b*c) i. Try the calculation (1 + 10i) * (2 + 20i). Your result should be: (1 + (10 * i)) * (2 + (20 * i)) = 198 + 40 i. This is correct because i^2 = 1. Remember I is the square root of –1.
24.1.5.4 Complex Division
Definition: (a + b i) / (c + d i) = (a*c –b*d)/(a^2 + b^2) + ((a*d + b*c)/(a^2 + b^2)) i. This definition seems very strange. The trick is that you trade the complex divisor in for a real number divisor. The way you do that is to multiply through by the complex conjugate of the divisor divided by itself which changes nothing since it is the same as multiplying by 1. Now, the complex conjugate is c  d i. Notice that the sign in front of the imaginary part is reversed (the meaning of the complex conjugate of a complex number). Plus is reversed to minus and minus to plus. Regrouping some factors, the numerator becomes (a + b I)*(c – d I). The denominator becomes (c – d I)*(c – d I) which is c^2 + d^2. Therefore, the quotient is (a*c + b*d+ (b*c  a*d) I)/(c^2 + d^2). However, this quotient does not exist if both c and d are 0. Try the calculation (15 + 55 I) / (7 + 9i). The result line should say: “((15) + (55 * i)) / (7 + (9 * i)) = 3 + 4 I”.
24.2 Conversions As with the calculator above, you are going to enter into the Google “search edit:” box the conversion you want performed. Then you are going to activate the “Search” button either by hitting ENTER or tabbing once to the “Search” button and hitting the SPACEBAR. If the Google conversion tool can perform the conversion, focus goes immediately to the “Search edit:” box. The lines shown in each example below is the result page.
24.2.1 Degrees And Radians
This conversion is relevant to the discussion of the trigonometric functions presented earlier. How many degrees are in 1 radian? In the “Search edit:” box, type “1 radian in degrees”, and then activate the “search” button. Your result page should look like this: Search

24.2.2 English Versus Metric System
Google can convert between the English and the metric system. How many meters are in 25 miles? In Google’s “Search edit:” box, type "25 miles in meters." Tab once to the “Search” button, and press the SPACEBAR. Beneath the line that says “Web”, you will find a line containing the answer.
24.2.3 Temperature Readings
Google can convert among Fahrenheit, Celsius, and Kelvin systems. For example, type “40 degrees Fahrenheit in Celsius” into the “Search edit:” box, and activate the “Search” button. You will see the following: “40 degrees Fahrenheit in Celsius  Google Search Sign in

24.2.4 Currency Conversion
Google can also convert currencies. Example 1: How many pesos are in a U. S. dollar (USD)? In the Google “Search edit:” box, type “1 USD in pesos”. Again, tab once to the “Search” button, and press the SPACEBAR. Focus moves into a page whose title is “1 USD in pesos”. The PC cursor will be on the “Search Edit:” box. Below it, you will find the following lines. “ Search

Google knows some science facts too. For example, type this into the “Search edit:” box – “speed of light in miles per second”. Arrowing down, you find the following: Table with 3 columns and 2 rows
the speed of light = 186 282.397 miles per second
More about calculator. table end Or, try the following: “solar mass in tons”. Google returns the following: “1 solar mass = 2.19240901 × 1027 short tons”. A short ton is a metric ton. If you want an English system ton, change the spelling of tons to “tones”. You then get the following result: “1 solar mass = 1.98892 × 1027 tonnes”.
Let’s inquire about a physical constant such as the gravitational constant. The “Search edit:” box should say “universal gravitational constant”. The result is “gravitational constant = 6.67300 × 1011 m3 kg1 s2”.
24.2.4 Miscellaneous Conversions
Google can also perform many other types of conversions. It can help out in the kitchen. Try these two conversions suggested by Google. • half a cup in teaspoons • 160 pounds * 4000 feet in Calories
Let’s end this chapter with an example that joins together the ideas in 24.1 and 24.2. It is a calculation and a conversion packaged together. Remember the above calculation determining the return on an investment of $50000 at 6% over 30 years? I want the result in Japanese currency. Here are the Google “Search edit:” and result. It is “50 000 * (1.06^30) Japanese yen = 2 364.16036 U.S. dollars”. . This is a puzzling result. Google took the 50000 to be in Yen. Here is a second attempt. I typed “50000*(1.06)^30 USD in Japanese currency” and got the result “50 000 * (1.06^30) U.S. dollars = 34.8830936 million Japanese yen”. This is the result I want. The problem in the first search I conducted was that I didn’t specify two currencies. Assuming that USD is a default is imperial thinking. The above is some of the things you can do with Google, but the coverage in this and the previous chapter was by no means exhaustive. So, have fun investigating Google for yourself.

Not sure, but the log of updates showed me that at some time in the last week my anniversary edition had the calculator updated. I have to say I've never found cause to use it so don't know what it used to do before!

When you enter an expression to be evaluated, it can’t contain a variable such as x or y or z. It can’t solve an equation. At the time I wrote this material, I didn’t find any statistical functions. Google may have added more capability over the past ten years. In the 1980’s Freedom Scientific was a company based in Arlington Texas. It had a selfvoicing engineering spreadsheet. It sat down and used it for about 30 minutes. It could solve equations. It could differentiate and integrate. The Scientific part of the company name was meaningful. Then another company bought it, and didn’t market this engineering spread sheet application. Too bad!

Right now I don't need any calc that can perform statistics, as Excel is enough for it, especially Excel 2016 which can draw some new charts like box plot. As I mentioned earlier when I tried a fresh new copy of NVDA on a Windows 10 virtual machine NVDA reads the calculator buttons fine, both with and without the Windows 10 App Essential add on. But NVDA did, however, refuse to read the changes made to the desplay, E.G when I pressed the backspace key to delete a number or the escape key to reset the display to 0.


Hi again, Right, so after getting my new laptop, upgraded to Windows 10 and then performed a clean reinstallation of Windows and installed NVDA and everything, along with Vocalizer and the Windows 10 App Essential add on, the calculator seems to work for a while but then after a reboot, which took longer because Windows was installing some updates I think, the calculator no longer work properly again, NVDA refuse to announce the keys that I've pressed.
