    Hi,

    You see it everywhere, Mathf.Clamp01, Mathf.Lerp, Mathf.PI, yet remains such a mystery as to why there is an f at the end. Why not just Math.Clamp and what does the 'f' stand for??

    float

    Standard .NET Math class uses double. Unity made a wrapping class that cast float into double and back into float for your convenience.

    So, function or float?

    @LightStriker: So are you saying the Mathf is in essence nothing but a wrapper class (around System.Math)?

    It's float. And yes, Mathf is a wrapper class that does all the casting for you.

    If you decompile it, yes, it is just that.

    Okay, thanks. Would it have been so hard to add one line in the docs that says: "f stands for float"??

    Unity is based on float. Only C# isn't by default. Not many people are bothered by the f :p

    Hahaha, I would if it was SOMEWHERE online. But for some reason the whole internet didn't have the answer to my question. :)
