itofix — Converts an integer to fixed point. Allegro game programming library.

Synopsis

#include <allegro.h>

fixed 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:

fixed number;
/* This conversion is OK. */
number = itofix(100);
ASSERT(fixtoi(number) == 100);
number = itofix(64000);
/* This check will fail in debug builds. */
ASSERT(fixtoi(number) == 64000);

Return Value

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