Square or involution operator

[mtrain]

I cant find it. What is the operator for square from the value or involution: 2^2, or sqrt16

IIRC there isn't one. Hopefully I am wrong, but if not you'll have to create a function that does it the hard way. See here for some hand formulas you could use.

I need to calculate:
Sqrt((Tx-x)^2+(Tz-z)^2)/(2*D*Fr/2)
The values are all variables, so this is just a math, but how can the script language have not those operators

I forget where but i have seen a line in one script

#include <math.h>

What does it mean? Maybe there is a way to connect a math function to a script to make calculation of square root or involution possible?
