Feature Request: Sqrt() for Pow()

[wolffy-au]

Hi - can you please add a squareroot function - Sqrt() to work in conjunction with the Pow() function?

I was going to do some fancy calculations orbital velocity across different planetary systems, but without square root I can't do:
v = Sqrt(GM / (radius + altitude))

The power function is, in fact, the square root function. Roots are just fractional powers.
