Description
See this accepted answer for a method to compare two cpp_dec_float's *without* including the guard digits in the comparison. Specifically see the second comment on the answer by "namezero".

(I find myself about to implement similar "epsilon" logic)

This is one for Christopher Kormanyos to answer really... but my guess is "by design".
Ideally we would have a true decimal type that rounded correctly... but it's hard to do both correctly and efficiently.
