# abs(3)

    NAME
         abs - integer absolute value

    SYNOPSIS
         #include <stdlib.h>

         int abs(int i)

    DESCRIPTION
         Abs returns the absolute value of its integer operand.

    SEE ALSO
         floor(3).

    BUGS
         Applying the abs function to the most negative integer generates a result
         which  is  the  most  negative integer.  That is, abs(0x80000000) returns
         0x80000000 as a result on a machine with 32-bit ints.  Using  the  result
         in unsigned computations is sound however.
