Static Methods
Method | Description |
|---|---|
| Abs | Returns the absolute value of |
| Acos | Returns the arc-cosine of f - the angle in radians whose cosine is f. |
| Approximately | Compares two floating point values and returns true if they are similar. |
| Asin | Returns the arc-sine of f - the angle in radians whose sine is f. |
| Atan | Returns the arc-tangent of f - the angle in radians whose tangent is f. |
| Atan2 | Returns the angle in radians whose Mathf.Tan is |
| Ceil | Returns the smallest integer greater than or equal to f. |
| CeilToInt | Returns the smallest integer greater to or equal to f. |
| Clamp | Clamps the given value between a range defined by the given minimum integer and maximum integer values. Returns the given value if it is within min and max. |
| Clamp01 | Clamps value between 0 and 1 and returns value. |
| ClosestPowerOfTwo | Returns the closest power of two value. |
| CorrelatedColorTemperatureToRGB | Convert a color temperature in Kelvin to RGB color. |
| Cos | Returns the cosine of angle f. |
| DeltaAngle | Calculates the shortest difference between two angles. |
| Exp | Returns e raised to the specified power. |
| FloatToHalf | Encode a floating point value into a 16-bit representation. |
| Floor | Returns the largest integer smaller than or equal to f. |
| FloorToInt | Returns the largest integer smaller to or equal to f. |
| GammaToLinearSpace | Converts the given value from gamma (sRGB) to linear color space. |
| HalfToFloat | Convert a half precision float to a 32-bit floating point value. |
| InverseLerp | Determines where a value lies between two points. |
| IsPowerOfTwo | Returns true if the value is power of two. |
| Lerp | Linearly interpolates between a and b by t. |
| LerpAngle | Same as Mathf.Lerp but makes sure the values interpolate correctly when they wrap around 360 degrees. |
| LerpUnclamped | Linearly interpolates between a and b by t with no limit to t. |
| LinearToGammaSpace | Converts the given value from linear to gamma (sRGB) color space. |
| Log | Returns the natural (base e) logarithm of a specified number. |
| Log10 | Returns the base 10 logarithm of a specified number. |
| Max | Returns the largest value. When comparing negative values, values closer to zero are considered larger. |
| Min | Returns the smallest of two or more values. |
| MoveTowards | Moves a value current towards target. |
| MoveTowardsAngle | Same as Mathf.MoveTowards but makes sure the values interpolate correctly when they wrap around 360 degrees. |
| NextPowerOfTwo | Returns the next power of two that is equal to, or greater than, the argument. |
| PerlinNoise | Generate 2D Perlin noise. |
| PerlinNoise1D | Generates a 1D pseudo-random pattern of float values across a 2D plane. |
| PingPong | PingPong returns a value that increments and decrements between zero and the length. It follows the triangle wave formula where the bottom is set to zero and the peak is set to length. |
| Pow | Returns f raised to power p. |
| Repeat | Loops the value t, so that it is never larger than length and never smaller than 0. |
| Round | Returns f rounded to the nearest integer. |
| RoundToInt | Returns f rounded to the nearest integer. |
| Sign | Returns the sign of f. |
| Sin | Returns the sine of angle f. |
| SmoothDamp | Gradually moves the current value towards a target value, over a specified time and at a specified velocity. |
| SmoothDampAngle | Gradually changes an angle given in degrees towards a desired goal angle over time. |
| SmoothStep | Interpolates between from and to with smoothing at the limits. |
| Sqrt | Returns square root of f. |
| Tan | Returns the tangent of angle f in radians. |
