There's one other major difference between the C99 notation and the current patch: the C99 notation includes a (hexa)decimal point. The advantages of this include:

- the exponent gives a rough idea of the magnitude of the number, and - the exponent doesn't vary with changes to the least significant bits of the float.

Is everyone agreed on a tohex/fromhex pair using the C99 notation as recommended in 754R?

Are you thinking of math module functions or as a method and classmethod on floats?
