Why does the exponent "rather" have a leading zero?  If the standard
mandates (or even allows) this, it is the only place where it specifies
a leading zero in a place where the programmer did not request it.

(And if so, why not pad it with more leading zeroes, so that a machine
that can handle exponents up to 75024 can say 1e+00003.)
