SYNOPSIS

        #include <allegro5/allegro.h>
        al_fixed al_fixsin(al_fixed x);

DESCRIPTION
This function finds the sine of a value using a lookup table. The input value must be a fixed point binary angle.

Example:

        al_fixed angle;
        int result;
        /* Set the binary angle to 90 degrees. */
        angle = al_itofix(64);
        /* The sine of 90 degrees is one. */
        result = al_fixtoi(al_fixsin(angle));
        assert(result == 1);

RETURN VALUE
Returns the sine of a fixed point binary format angle as a fixed point value.
