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.
The disadvantage is the loss of evalability. (Is that a word?)
