How to take square roots in JASS

[bane25]

Just a quick question, who do you take square roots of reals in JASS?
If it matters, I am doing this for the equivalent of the distance formula.

native SquareRoot takes real x returns real

You could always just raise the value to the power of 0.5

eg.
25 ^ 0.5 = 5

Either of the two above solutions work, but seeing as you're doing the distance formula, it's actually faster to do:

if x > y * y then
endif

than it is to do:

if SquareRoot(x) > y then
endif
