NAME

       al_fixdiv - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              al_fixed al_fixdiv(al_fixed x, al_fixed y);

DESCRIPTION

       A  fixed  point  value can be divided by an integer with the normal / operator.  To divide
       two fixed point values, though, you must use this function.  If a division by zero occurs,
       Allegro’s  errno will be set and the maximum possible value will be returned, but errno is
       not cleared if the operation is successful.  This means that if you are going to test  for
       division by zero you should call al_set_errno(0) before calling al_fixdiv(3alleg5).

       Example:

              al_fixed result;

              /* This will put 0.06060 `result'. */
              result = al_fixdiv(al_itofix(2), al_itofix(33));

              /* This will put 0 into `result'. */
              result = al_fixdiv(0, al_itofix(-30));

              /* Sets errno and puts -32768 into `result'. */
              result = al_fixdiv(al_itofix(-100), al_itofix(0));
              assert(!al_get_errno()); /* This will fail. */

RETURN VALUE

       Returns  the  result of dividing x by y.  If y is zero, returns the maximum possible fixed
       point value and sets Allegro’s errno to ERANGE.
