Additional math functions

math.hypot New in version 95

 ( 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 New in version 95

 ( 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 New in version 95

 ( number x, number min, number max ) -> number
 Returns x clamped to min and max boundaries.
