How do I raise X to the power of Y in Powershell?

Question 1

I (apparently wrongly) assumed there would be a built-in power operator or function in Powershell, but I it seems there is not, or is there?

Question 2

As you’ve found, real exponentation can be achieved with some accuracy by calling [Math]::Pow().

For large integer exponentiation, you might want to use [bigint]::Pow() instead:

PS ~> [Math]::Pow(256, 20)
1.4615016373309E+48
PS ~> [bigint]::Pow(256, 20)
1461501637330902918203684832716283019655932542976
