<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> local easedFraction = math.ease.InSine(.25) --25% progress is now eased in using sine.⤶ ⤶ print(Lerp(.25, 0, 1)) print(Lerp(easedFraction, 0, 1)) print(Lerp(.25, 0, 5))⤶ print(Lerp(easedFraction, 0, 5))⤶ -- 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 0.07612...⤶ ⤶ 0.38060233744357⤶ 1.25 0.38060...⤶ ```⤶ </output> </example> </summary> </type>
