- <h2>Properties</h2>
- <h2>Methods</h2>
- <h3>[method:Float clamp]( [page:Float x], [page:Float a], [page:Float b] )</h3>
- <div>
- x — Value to be clamped.<br />
- a — Minimum value<br />
- b — Maximum value.
- </div>
- <div>
- Clamps the *x* to be between *a* and *b*.
- </div>
- <h3>[method:Float clampBottom]( [page:Float x], [page:Float a] )</h3>
- <div>
- x — Value to be clamped.<br />
- a — Minimum value
- </div>
- <div>
- Clamps the *x* to be larger than *a*.
- </div>
- <h3>[method:Float mapLinear]( [page:Float x], [page:Float a1], [page:Float a2], [page:Float b1], [page:Float b2] )</h3>
- <div>
- x — Value to be mapped.<br />
- a1 — Minimum value for range A.<br />
- a2 — Maximum value for range A.<br />
- b1 — Minimum value for range B.<br />
- b2 — Maximum value for range B.
- </div>
- <div>
- Linear mapping of *x* from range [*a1*, *a2*] to range [*b1*, *b2*].
- </div>
- <h3>[method:Float random16]()</h3>
- <div>
- Random float from 0 to 1 with 16 bits of randomness.<br />
- Standard Math.random() creates repetitive patterns when applied over larger space.
- </div>
- <h3>[method:Integer randInt]( [page:Integer low], [page:Integer high] )</h3>
- <div>
- Random integer from *low* to *high* interval.
- </div>
- <h3>[method:Float randFloat]( [page:Float low], [page:Float high] )</h3>
- <div>
- Random float from *low* to *high* interval.
- </div>
- <h3>[method:Float randFloatSpread]( [page:Float range] )</h3>
- <div>
- Random float from *- range / 2* to *range / 2* interval.
- </div>
- <h3>[method:Float sign]( [page:Float x] )</h3>
- <div>
- Returns -1 if *x* is less than 0, 1 if *x* is greater than 0, and 0 if *x* is zero.
- </div>
- <h3>[method:Float degToRad]([page:Float degrees])</h3>
- <div>
- degrees -- [page:Float]
- </div>
- <div>
- Converts degrees to radians.
- </div>
- <h3>[method:Float radToDeg]([page:Float radians])</h3>
- <div>
- radians -- [page:Float]
- </div>
- <div>
- Converts radians to degrees
- </div>
- <h3>[method:Float smoothstep]([page:Float x], [page:Float min], [page:Float max])</h3>
- <div>
- x -- The value to evaluate based on its position between min and max. <br />
- min -- Any x value below min will be 0 <br />
- max -- Any x value above max will be 1
- </div>
- <div>
- Returns a value between 0-1 that represents the percentage that x has moved between min and max, but smoothed or slowed down the closer X is to the min and max.<br/><br/>

- </div>
- <h3>[method:Float smootherstep]([page:Float x], [page:Float min], [page:Float max])</h3>
- <div>
- x -- The value to evaluate based on its position between min and max. <br />
- min -- Any x value below min will be 0 <br />
- max -- Any x value above max will be 1
- </div>
- <div>
- Returns a value between 0-1. It works the same as smoothstep, but more smooth.
- </div>
