+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.
