Fixed point sine of binary angles.


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.
