Are there any easing functions built into Unity 5?

Question

Besides Lerp and SLerp, does Unity have any sort of easing functions built in, say if you wanted to move an object from point A to point B in exactly 2 seconds with a "Cubic ease-in"?

This seems like something that should be built into any game library, but I can't find any reference to it. I have been having a difficult time Googling this; what have been finding (among a whole lot of unrelated or completely incorrect stuff) are the occasional function written by individual forumers.

Is there proper easing built into Unity 5, or am I going to spend my weekend porting Robert Penner's easing functions? (I don't mind, I just don't want to do the work and realize on Monday it already existed).

The mathfx library provides the most common interpolation functions, including hermite/sinerp/coserp/berp. There's a C# implementation for Unity here: http://wiki.unity3d.com/index.php?title=Mathfx

If you want to define an arbitrary easing function, it's trivial to create an AnimationCurve parameter and evaluate the value of the curve at any position between 0-1, then pass that value into Lerp().

That is in the right direction. Just to be clear, Mathfx is a user contributed library (and by "library", I mean that C# class you have to save as a file), correct? There's no easing or tweening built into Unity?
