**NAME**

fixdiv - Fixed point division. Allegro game programming library.

**SYNOPSIS**

#include<allegro.h>fixedfixdiv(fixedx,fixedy);

**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.
