Absolute value of NSInteger

Question

Referring to Convert to absolute value in Objective-C I\'m wondering if there are functions for NS typedefed types. Or is abs(NSInteger) okay? Is it architecture-sa

Answer 1

You can use Foundation’s ABS() macro:

NSInteger a = 5;
NSInteger b = -5;
NSLog(@"%ld %ld", ABS(a), ABS(b));
