I keep a PowerShell console open at all times. I find it to be an excellent replacement for the Windows Calculator for quick calculations. Arithmetic operators are part of the PowerShell language, so they can be used directly at the prompt. For mathematical operations like square root, logarithm and those from trigonometry, the
System.Math class from the .Net Framework can be used.
For example, to find the square root we can call the
Sqrt() method from the
[System.Math]::Sqrt( 20 )
An easier way to do the same is:
[math]::sqrt( 20 )
This shorter case-insensitive version works because PowerShell is designed for an easy console experience. So, in PowerShell all the
System.* classes can be invoked without the
System prefix. Also, PowerShell tries to be as case-insensitive as possible, so most class and method names can be called ignoring the case.
