Note: If you just want to wrap between 0.0 and [code]n[/code] (where [code]n[/code] is a positive float value) then it's better for performance to use [method fmod] method like [code]fmod(number, n)[/code].
The usage of [code]wrapf[/code] is more flexible than using the [method fmod] approach by giving the user a simple control over the minimum value. It also fully supports negative numbers, e.g.
[codeblock]
# infinite rotation (in radians)
angle = wrapf(angle + 0.1, -PI, PI)
