Functions

acos(num x) → double

Converts x to a double and returns its arc cosine in radians.

asin(num x) → double

Converts x to a double and returns its arc sine in radians.

atan(num x) → double

log(num x) → double

Converts x to a double and returns the natural logarithm of the value.

max<T extends num>(T a, T b) → T

Returns the larger of two numbers.

min<T extends num>(T a, T b) → T

Returns the lesser of two numbers.

pow(num x, num exponent) → num

Returns x to the power of exponent.

sin(num radians) → double

Converts radians to a double and returns the sine of the value.

sqrt(num x) → double

Converts x to a double and returns the positive square root of the value.

tan(num radians) → double

Converts radians to a double and returns the tangent of the value.
