Windows калькулятор с историей

Many people who prefer typing instead of clicking the calculator buttons in the Windows normally found the Calculator with Graphic window is not so convenient. So you want to find an alternative to Windows Calculator but don’t want to install any new software? Then you must consider using Powershell as your calculator.

PS C:\> #Below will do an addition function. Please note # is a comment in Powershell.
PS C:\> 21 + 38
59
PS C:\> #Below will do a minus function.
PS C:\> 50 - 25
25
PS C:\> #Below will do a multiply function. In Powershell, * is multiply. And it not always need to have space between operands.
PS C:\> 12*13
156
PS C:\> #Below will do a division function. In Powershell, / is division.
PS C:\> 60.2/12

PS C:\> # Assign 35 to variable A. $ symbol is the variable declaration.
PS C:\> $A=35
PS C:\> $A
35
PS C:\> $A+15
50
PS C:\> $B=2
PS C:\> $A*$B
70
PS C:\> # We can assign them to a new variable also.
PS C:\> $C=$B*$A
PS C:\> $C
70

Advanced functions

Powershell also supports many advanced math functions via .NET System.Math class. Below is the list of the functions

You can access the Math functions via [Math]::. Below are some of the examples usage.

PS C:\> [Math]::Pow(10, 2)
100
PS C:\> [Math]::Log10(100)
2
PS C:\> [Math]::PI
3.14159265358979

Finally, I think the most convenient part is the History support as you always able to check back what you have calculated from the console screen :).
