 * 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.

 *
