* Description:

* 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.

*
