You'd need to have it in writing, wouldn't you?
The only spec I know of promises no such thing:

We know that Python floats are equivalent to C doubles, which are 64-bit
IEEE-754 floating point numbers.
Well, actually, C doubles are not strictly defined. The only promise the C
standard makes is that double is no smaller than float. (That's C float,
not Python float.) And of course, not all Py
