fixdiv(3)			Allegro	manual			     fixdiv(3)

NAME
       fixdiv -	Fixed point division. Allegro game programming library.

SYNOPSIS
       #include	<allegro.h>

       fixed fixdiv(fixed x, 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, `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 set `errno=0' before calling  fixdiv().
       Example:

	  fixed	result;
	  /* This will put 0.06060 `result'. */
	  result = fixdiv(itofix(2), itofix(33));
	  /* This will put 0 into `result'. */
	  result = fixdiv(0, itofix(-30));
	  /* Sets `errno' and puts -32768 into `result'. */
	  result = fixdiv(itofix(-100),	itofix(0));
	  ASSERT(!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 `errno' to ERANGE.
