Thanks for the comments. Here's an updated patch, that actually makes use of
the pure Python version to test the built-in int-to-float conversion.

I see there is already something similar for true division.
I find
+q_max, shift_max = 1 sig_bits, sys.float_info.max_exp - sig_bits
easier to read as two lines
+q_max = 1 sig_bits
+shift_max = sys.float_info.max_exp - sig_bits
New submission from Mark Dickinson dicki...@gmail.com:
It would be helpful (perhaps to developers of alternative implementations) to
give a pure Python version of correctly-rounded long-to-float conversion.
Attached is such a version, as a patch to test_long in the release27-maint
branch.
