Functions

min(num a, num b) → num
Returns the lesser of two numbers.
max(num a, num b) → num
Returns the larger of two numbers.
atan2(num a, num b) → double
A variant of atan.
pow(num x, num exponent) → num
Returns x to the power of exponent.
sin(num x) → double
Converts x to a double and returns the sine of the value.
cos(num x) → double
Converts x to a double and returns the cosine of the value.
tan(num x) → double
Converts x to a double and returns the tangent of the value.
acos(num x) → double
Converts x to a double and returns the arc cosine of the value.
asin(num x) → double
Converts x to a double and returns the arc sine of the value.
atan(num x) → double
Converts x to a dobule and returns the arc tangent of the value.
sqrt(num x) → double
Converts x to a double and returns the positive square root of the value.
exp(num x) → double
Converts x to a double and returns the natural exponent, E, to the power x.
log(num x) → double
Converts x to a double and returns the natural logarithm of the value.
