/* FUNCTION <<abs>>---integer absolute value (magnitude) INDEX abs ANSI_SYNOPSIS #include <stdlib.h> int abs(int <[i]>); TRAD_SYNOPSIS #include <stdlib.h> int abs(<[i]>) int <[i]>; DESCRIPTION <<abs>> returns @tex $|x|$, @end tex the absolute value of <[i]> (also called the magnitude of <[i]>). That is, if <[i]> is negative, the result is the opposite of <[i]>, but if <[i]> is nonnegative the result is <[i]>. The similar function <<labs>> uses and returns <<long>> rather than <<int>> values. RETURNS The result is a nonnegative integer. PORTABILITY <<abs>> is ANSI. No supporting OS subroutines are required. */ #include <stdlib.h> int _DEFUN (abs, (i), int i) { return (i < 0) ? -i : i; }
