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.
