Using fabsf on CGFloats shows a warning

Question

I'm trying to get the absolute value of a CGFloat parameter but I'm getting the following warning:

Absolute value function 'fabsf' given an argument of type 'CGFloat' (aka 'double') but has parameter of type 'float' which may cause truncation of value

A CGFloat is a double on 64 bit platforms, but you're passing it to a function that expects a single precision float - use fabs instead here. — Paul R, Jul 20 '15 at 06:28
I just realized that and posted an answer to my question - thanks! — YogevSitton, Jul 20 '15 at 06:28

A CGFloat is a double on 64 bit platforms, but you're passing it to fabsf, which expects a single precision float - use fabs instead, which takes a double as an argument.
