The attached patch drastically speeds up PyLong_AsDouble for single digit longs:


-m timeit -s "x=2" "x*2.2 + 2 + x*2.5 + 1.0 - x / 2.0 + (x+0.1)/(x-0.1)*2 + (x+10)*(x-30)"

with patch: 0.414
without: 0.612

spectral_norm: 1.05x faster.    The results are even better when paired with patch from issue #21955.
