Function wrap

Wraps floating point numbers to be within a range (default: 0..1). Use wrapInteger if you want to wrap integer values.

This logic makes sense for some things like rotation angle.

If you just want to lock values to a range without wrapping, consider clamp.

wrap(1.2);   // 0.2
wrap(2);     // 1.0
wrap(-0.2); // 0.8
Copy

A range can be provided too:

wrap(30, 20, 50);  	 // 30
wrap(60, 20, 50);    //  30
Copy
