Additional math functions (added in: 94.1.1311)
math.hypot
( number x, number y ) -> number
Returns the length of hypotenuse of right angle triangle with sides x and y, equivalent
to sqrt(x*x + y*y), but has better numerical stability and internaly handles intermediate
overflows/underflows, but is also slower.
math.diag
( number x1 [, ... ] ] ) -> number
Returns the length of diagonal of an n-dimensional box. Rather quick method that does not
handle intermediate overflows/underflows nor is made for numerical stability.
math.clamp
( number x, number min, number max ) -> number
Returns x clamped to min and max boundaries.
