al_itofix (3alleg5)

• #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".

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);
  
  

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

al_fixtoi(3alleg5), al_ftofix(3alleg5), al_fixtof(3alleg5).
