fixsin - Man Page

#include <allegro.h>

fixed fixsin(fixed x);

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);

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