math.hypot(x, y)
^ Get the hypotenuse of a triangle with legs x and y.
Useful for distance calculation.
math.sign(x, tolerance)
^ Get the sign of a number
Optional: Also returns 0 when the absolute value is within the tolerance (default 0)
string:split(separator)
^ e.g. string:split("a,b", ",") == {"a","b"}
string:trim()
