Are there actually any Python implementations or builds which have floats not equal to 64 bits? If not, perhaps it is time to make 64 bit floats a language guarantee.
This will be unfortunate when Intel bring out a processor with 256-bit floats (or by "64 bit" do you mean "at least 64 bit"?). Hm, is there an analog of Moore's law that says the number of floating-point bits doubles every X years? :-)
Unrelated thought: Users might be unsure if the exponent in a hexadecimal float is in decimal or in hex.
