-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
Could you extend a test case for this block with Python? This might reveal issues with the implementation more easily. Also, others might benefit from it. For your specific problem, I guess the GR block result is as close as it gets for a LUT-based calculation. And it's not off by a lot but by some 10^-x.
