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