fixdiv(3alleg4) Allegro manual fixdiv(3alleg4)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 fix-
div(). 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.

Hello Friends,
Why I am not getting exact result in the following division. It is rounding off automatically. Is there any way to get the exact result or
can be set by user to get how many digits to carry after the decimal.

Hey, Can I assume that for certain function calls, errno can never be set to a certain value.
More specifically, can I assume that for if the stat function call fails, the errno can never be or "No space left on device."
I am assuming that a read function cannot fail because of no space... (5 Replies)
