Information AboutWindows Calculator |
Microsoft Calculator is a Calculation Application included with all Microsoft Windows Operating System s. OVERVIEW
in Scientific mode.]] Calculator has been included with every release of Microsoft Windows, but the user interface and the core feature set, has largely remained unchanged in form and function since Windows 95 . The Calculator in Windows 2000 and later Windows NT-based versions uses an Arbitrary-precision Arithmetic library, replacing the standard IEEE Floating Point library. The Old New Thing blog by Raymond Chen: When you change the insides, nobody notices It offers infinite precision for basic operations (addition, subtraction, multiplication, division) and 32 digits of precision for advanced operations (square root, transcendental operators). Many specialized keyboards have a "calculator" key, which launches Calculator by default. BUGS The version of Calculator shipped with calculations with insufficient accuracy as they are prone to yield wrong results in calculations with numbers that cannot be accurately represented in binary. The modern versions, described above, eliminate this bug. Calculator since Windows 3.0 has had the 'sqrt' button available only in the standard mode. Switching over to scientific mode will make this button disappear. There is no fix, but Microsoft suggests raising numbers to the half power (e.g. 144 ^ .5 ), Square Root (sqrt) in Calculator's Scientific Mode even though selecting the 'inv' checkbox and clicking 'x^2' button will provide the square root function. OPTIONAL CALCULATOR REPLACEMENTS Microsoft has released two other calculator applications to the Microsoft Download Center, both of which offer features not found in the Calculator included with Windows.

Calculator Plus also provides an alternate interface. '' Power Calculator '' - Released as a Windows XP PowerToy . Power Calculator supports graphing. Although the program allows user to adjust the precision of calculations, there are flaws in the implementation. For example, the program produces an erroneous graph for the function .
