- *
- * The function calculates the i/q coordinate for a given angle using
- * cordic algorithm. The coordinate consists of a real (i) and an
- * imaginary (q) part. The real part is essentially the cosine of the
- * angle and the imaginary part is the sine of the angle. The returned
- * values are scaled by 2^16 for precision. The range for theta is
- * for -180 degrees to +180 degrees. Passed values outside this range are
- * converted before doing the actual calculation.
