From GMLwiki

This library provides basich mathematical functions for the GML Interpreter

aNormal		chooses a unit vector v’ such that v v’ dot is zero, ie. v’ is perpendicular to v
abs		b is ’a a mul sqrt’.
acos		computes the inverse cosine function
add		adds two elements
and		returns 1 iff both a and b do not equal 0
asin		computes the inverse sines function
atan		computes the arcus tangens
atan2		returns the arctangent of y/x in the range -180 to 180
ceiling		b equals a iff ’a 1.0 mod’ equals 0.0. otherwise b equals ’dup 1.0 mod sub 1 add’ except that it is an int
clamp		clamps float t to the float interval
cos		computes the cosine function
cross		returns the cross product of u and v
determinant		computes 2x2 or 3x3 determinant
dist		d is the distance between points p0 and p1
div		divides an number or point through a number.
exp		computes the exp(a) exponential function (to basis e)
floor		b equals a iff ’a 1.0 mod’ equals 0.0. otherwise b equals ’dup 1.0 mod sub’ except that it is an int.
getX		get X component of a point
getY		get Y Component of a point
getZ		get Z Component of a point
inv		inverts a number
ln		computes the natural logarithm of a (basis e)
log		computes the decimal logarithm of a
mod		computes c as a modulo b
mul		multiplies two objects which can be numbers or points
neg		negates an object
normalize		computes the unit length of a point
not		returns 1 iff a equals 0 or 0.0
or		returns 1 iff either a or b or both do not equal 0 (or 0.0)
pi		returns 3.4159265359
planemul		computes w = x*u + y*v
pow		takes a to the power of b.
putX		replaces a point’s x coordinate.
putY		replaces a point’s y coordinate.
putZ		replaces a point’s z coordinate.
random		return random number
round		rounds a float to the nearest integer
sin		computes the sines function
sqrt		computes the square root of a number.
sub		substracts b from a
tan		computes the tangens function
trunc		chops off the decimal digits after the point
vector2		turns two numbers into a P2
vector3		turns three numbers into a P3
