i've been looking around trying to find a method that calculates the
|absolute value| of a number.
Without success.
Does anyone know if such a function exists?
This is really a C programming task (and a trivial one at that) rather
than a Cocoa problem.
For the specific case of |x-y| that you give in your subject line you
can use:
absoluteValue = (x>y) ? x-y : y-x;
I'll leave it as an exercise to the reader to work out how to deal with
more general cases.
