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.SEE ALSO
