The reason for creating float (IEEE or previous hacks) is that people want to do ℝ-ish stuff. The only justification for float is that it is consistent with ℝ [Is it? Aint it? Depends on how you squint]¹ Nobody wants to do float for the sake of float. The only parties that (presumably) want to do "pure" float (ie ignore ℝ completely) are the h/w-guys who need to get an "IEEE-compliant" stamp. ============= ¹ Even the IEEE standard writers need to do a tight-rope walk between - respecting ℝ - making a spec that is 'hardware-able" - And will not have us software-guys screaming Ie There is no one (I can think of) except hw engineers who would care to think float without minding ℝ. -- https://mail.python.org/mailman/listinfo/python-list
