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.
