BCD can accurately represent reals which are exact decimal fractions.
Binary can accurately represent reals which are exact binary fractions.
Those are both small subsets of the complete set of reals.
I could imagine a quality implementation using either encoding. Which is
faster may well turn out to be dependedent upon the type of problem
encountered.
