Proposed patch makes float.fromhex() faster for exact float. $ ./python -m timeit -s "h = float.hex(1.23)" -- "float.fromhex(h)" Unpatched: 1000000 loops, best of 3: 0.886 usec per loop Patched: 1000000 loops, best of 3: 0.519 usec per loop |

A mistake in using PyObject_CallFunctionObjArgs() caused a crash in using fromhex() for subclasses. New tests added in issue23640 covers this case. |
