But I would like to leave it alone. Extended precision simply is not an issue on any current platform I'm aware of ("not even Windows"), and I would, e.g., hate trying to explain to users why

    1 / 2731 != 1.0 / 2731.0

(assuming we're not also proposing to take float division away from the HW). It's A Feature that

    I / J == float(I) / float(J)

whenever I and J are both representable as floats.

If extended precision is an issue on some platform, fine, let them speak up. On x87 we could document that CPython assumes the FPU's "precision control" is set to 53 bits.
