NAME

fixsin - Fixed point sine of binary angles. Allegro game programming library.

SYNOPSIS

#include <allegro.h>

fixed fixsin(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: 
    fixed angle;
    int result;
    
    /* Set the binary angle to 90 degrees. */
    angle = itofix(64);
    /* The sine of 90 degrees is one. */
    result = fixtoi(fixsin(angle));
    ASSERT(result == 1);

RETURN VALUE

Returns the sine of a fixed point binary format angle. The return value will be in radians.
