NAME

al_itofix - Allegro 5 API

SYNOPSIS

#include <allegro5/allegro.h>
al_fixed al_itofix(int x);
    

DESCRIPTION

Converts an integer to fixed point. This is the same thing as x<<16. Remember that overflows (trying to convert an integer greater than 32767) and underflows (trying to convert an integer lesser than -32768) are not detected even in debug builds! The values simply “wrap around”.

Example:

al_fixed number;
/* This conversion is OK. */
number = al_itofix(100);
assert(al_fixtoi(number) == 100);
number = al_itofix(64000);
/* This check will fail in debug builds. */
assert(al_fixtoi(number) == 64000);
    

RETURN VALUE

Returns the value of the integer converted to fixed point ignoring overflows.
