I am baffled in the difference of this two in xcode, ABS(A) and abs(int). Cant seem to find ay explanation online as well. Which should I use? I am actually working on an accelerometer. Using ABS(A) and abs(int) gives me two different values. Using abs(int) would result in an inf value at times, while ABS(A) would give me a different value but never inf. Thanks!

abs()works on int, meaningabs(-10.123)would return10, whileABS()is a macro fromNSObjCRuntime.hwhich returns a value whose type is the type of the argument.
