  The function supports two configurations, depending on the sign attribute of a:
- If a is signed, the allowed input range is [-π,+π] and the output range for the sine and cosine is in [−1,1].
 - If a is unsigned, the IP core restricts the input to [0,+π/2] and restricts the output range to [0,1].
