.SH SYNOPSIS
.IP
.nf
\f[C]
#include\ <allegro5/allegro.h>

al_fixed\ al_itofix(int\ x);
\f[]
.fi
.SH DESCRIPTION
.PP
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".
.PP
Example:
.IP
.nf
\f[C]
\ \ \ \ 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);
\f[]
.fi
