Usage

All easing functions take a float64 and return a float64. The input should be between 0 and 1, inclusive.

t = ease.OutElastic(t)

Some easing functions have extra parameters, like period. Here is an example:

var f ease.Function
f = ease.OutElasticFunction(0.5)
t = f(t)

Or, simply...

t = ease.OutElasticFunction(0.5)(t)
