the point is, there are still unrepresentables (1&#x2F;3 e.g.) in binary encoded decimal.  If it&#x27;s all about literals, just make the user put the correct literal in, and make them understand that floats are imperfect anyways.  If you&#x27;re doing anything remotely useful with Binary Coded Decimal, probably about two or three operations in, you&#x27;re going to lose resolution on your exactness.  It doesn&#x27;t buy you much.  GIGO.
