Math                  Description Methods 
abs(x)                Returns the absolute value of x. 
acos(x)               Returns the arc cosine of x in radians. 
asin(x)               Returns the arc sine of x in radians. 
atan(x)               Returns the arc tangent of x in radians. 
atan2(y,x)            Returns the arc tangent of the quotient of its Arguments, that is, y/x. 
ceil(x)               Returns the smallest integer greater than or equal to x. 
cos(x)                Returns the cosine of x. 
exp(x)                Returns ex, where x is the Argument and e is Euler's constant. 
floor(x)              Returns the largest integer less than or equal to x. 
log(x)                Returns the natural logarithm (base E) of x. 
max(x,y)              Returns the greater of the two numbers x and y. 
min(x,y)              Returns the lesser of the two numbers x and y. 
pow(x,y)              Returns xy, traditionally base to the exponent power, that is, baseexponent. 
random()              Returns a pseudo-random number between 0 and 1. 
round(x)              Returns the value of x rounded to the nearest integer with .50 as cutoff. 
sin(x)                Returns the sine of x. 
sqrt(x)               Returns the square root of x. 
tan(x)                Returns the tangent of x.
