I haven't seen a (modern) language without it.

C: sqrt (#include <math.h>)
C++: std::sqrt (#include <cmath>)
Java: Math.sqrt

Hey man! This is the Pythagoras theorem!

However this is the code

A = (x1, y1, z1)
B = (x2, y2, z2)

d = sqrt( (x2-x1)2 + (y2-y1)2 + (z2-z1)2 )

For C++.NET the square root function is Math::Sqrt().
