Class Functions

Sin	Returns the sine of angle f in radians.
Cos	Returns the cosine of angle f in radians.
Tan	Returns the tangent of angle f in radians.
Asin	Returns the arc-sine of f - the angle in radians whose sine is f.
Acos	Returns the arc-cosine of f - the angle in radians whose cosine is f.
Atan	Returns the arc-tangent of f - the angle in radians whose tangent is f.
Atan2	Returns the angle in radians whose Tan is `y/x`.
Sqrt	Returns square root of f.
Abs	Returns the absolute value of f.
Min	Returns the smallest of two or more values.
Max	Returns largest of two or more values.
Pow	Returns f raised to power p.
Exp	Returns e raised to the specified power.
Log	Returns the logarithm of a specified number in a specified base.
Log10	Returns the base 10 logarithm of a specified number.
Ceil	Returns the smallest integer greater to or equal to f.
Floor	Returns the largest integer smaller to or equal to f.
Round	Returns f rounded to the nearest integer.
CeilToInt	Returns the smallest integer greater to or equal to f.
FloorToInt	Returns the largest integer smaller to or equal to f.
RoundToInt	Returns f rounded to the nearest integer.
Sign	Returns the sign of f.
Clamp	Clamps a value between a minimum float and maximum float value.
Clamp01	Clamps value between 0 and 1 and returns value.
Lerp	Interpolates between a and b by t. t is clamped between 0 and 1.
LerpAngle	Same as Lerp but makes sure the values interpolate correctly when they wrap around 360 degrees.
MoveTowards	Moves a value current towards target.
MoveTowardsAngle	Same as MoveTowards but makes sure the values interpolate correctly when they wrap around 360 degrees.
SmoothStep	Interpolates between min and max with smoothing at the limits.
Approximately	Compares two floating point values if they are similar.
SmoothDamp	Gradually changes a value towards a desired goal over time.
SmoothDampAngle	Gradually changes an angle given in degrees towards a desired goal angle over time.
Repeat	Loops the value t, so that it is never larger than length and never smaller than 0.
PingPong	PingPongs the value t, so that it is never larger than length and never smaller than 0.
InverseLerp	Calculates the Lerp parameter between of two values.
ClosestPowerOfTwo	Returns the closest power of two value.
GammaToLinearSpace	Converts the given value from gamma to linear color space.
LinearToGammaSpace	Converts the given value from linear to gamma color space.
IsPowerOfTwo	Returns true if the value is power of two.
NextPowerOfTwo	Returns the next power of two value.
DeltaAngle	Calculates the shortest difference between two given angles.
PerlinNoise	Generate 2D Perlin noise.
