But why MIN macros?

Revision en1, by -is-this-fft-, 2016-03-28 15:22:42

I often, not that often, but still often see things like this while hacking:

#define MIN(a,b) (a) < (b) ? (a) : (b)
#define MAX(a,b) (a) > (b) ? (a) : (b)
#define ABS(a) (a) > 0 ? (a) : -(a)


While these are not as common as other (dubious) preprocessor macros, I still see these being used fairly commonly. There are, in my opinion, several downsides to using these -- if the inputs were functions, one of them gets executed twice.

So I want to ask, is there any advantage to using these over std::min(a, b) and others?
