<h2>Methods</h2>

<h3>.clamp( [page:Float x], [page:Float a], [page:Float b] ) [page:Float]</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>.clampBottom( [page:Float x], [page:Float a] ) [page:Float]</h3>
<div>
x — Value to be clamped.<br />
a — Minimum value
</div>
<div>
Clamps the *x* to be larger than *a*.
</div>

<h3>.mapLinear( [page:Float x], [page:Float a] ) [page:Float]</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>.random16() [page:Float]</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>.randInt( [page:Integer low], [page:Integer high] ) [page:Integer]</h3>
<div>
Random integer from *low* to *high* interval.
</div>

<h3>.randFloat( [page:Float low], [page:Float high] ) [page:Float]</h3>
<div>
Random float from *low* to *high* interval.
</div>

<h3>.randFloatSpread( [page:Float range] ) [page:Float]</h3>
<div>
Random float from *- range / 2* to *range / 2* interval.
</div>
