Description

These are the standard easing equations. All of the functions in this module expect a fractional between 0 and 1, and give back a fractional between 0 and 1. Some eases require some configuration. These options are provided via types with default instances.

Documentation

type Ease a = Fractional a => a -> a Source #

An Ease is just a function from some fractional to another fractional. Eases expects a term between 0 and 1 and gives a term between 0 and 1. This is not statically checked, but maybe should be.
