itofix(3)                       Allegro manual                       itofix(3)



NAME
       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.
