<type name="math.ease" category="libraryfunc" is="library"> <summary>An easing library that allows you to interpolate with various kinds of smoothing [functions](https://easings.net/). To use with <page>Global.Lerp</page>, input what you would to the fraction argument in one of these easing functions and then the output of that into the <page>Global.Lerp</page> fraction argument. <example> <description>Example usage with Lerp and <page>math.ease.InSine</page></description> <code> -- Define a wrapper function to make it easier to work with local function easedLerp(fraction, from, to) return Lerp(math.ease.InSine(fraction), from, to) end -- Compare with the non-eased version of Lerp print(easedLerp(0.25, 0, 1)) print(Lerp(0.25, 0, 1)) print(easedLerp(0.25, 0, 5)) print(Lerp(0.25, 0, 5)) </code> <output> ``` 0.076120467488713 0.25 0.38060233744357 1.25 ``` </output> </example> <example>⤶ A brief visual example of different easing methods⤶ <image src="https://i.imgur.com/XZPgymK.gif"/>⤶ </summary> <added>2021.12.15</added> </type>
