 hmm, hmm, i think i got it: it's not that the exponent is needed to
be even, it's that the mantissa needs to be an even number of bits.
does that make sense?

 it would mean that MSBHigh doesn't need to be adjusted: just the
number of extra bits to FPNumBase should be adjusted to accommodate an
even number of bits.
