NAME
fixcos - Fixed point cosine of binary angles. Allegro game programming library.SYNOPSIS
#include <allegro.h>fixed fixcos(fixed x);
DESCRIPTION
This function finds the cosine of a value using a lookup table. The input value must be a fixed point binary angle. Example:fixed angle; float result; /* Set the binary angle to 45 degrees. */ angle = itofix(32); /* The cosine of 45 degrees is about 0.7071. */ result = fixtof(fixcos(angle)); ASSERT(result > 0.7 && result < 0.71);
RETURN VALUE
Returns the cosine of a fixed point binary format angle. The return value will be in radians.SEE ALSO
