Obtains the absolute value (intmax_t type).
intmax_t __far imaxabs(intmax_t j); (C99)
Returns the absolute value of j (size of j), | j |. If the input value of imaxabs is the smallest negative value, the same value is returned.
This function obtains the absolute value of j (size of j), | j |. If j is a negative number, the result is the reversal of j. If j is not negative, the result is j.
