al_itofix - Man Page

Allegro 5 API


#include <allegro5/allegro.h>

al_fixed al_itofix(int x);


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”.


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.
