# Easing Functions in Go

### Installation

    go get -u github.com/fogleman/ease

### Documentation

[https://godoc.org/github.com/fogleman/ease](https://godoc.org/github.com/fogleman/ease)

### 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)
