+* 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]>;
+* <<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.
