Bug in dc

[Russell Harper]

Literal real values in bases other than 10 lose precision, e.g.

$ dc <<<'16 d i o F423F.FD p'
F423F.FA

Would expect the output to be F423F.FD

It basically makes the calculator useless for non-decimal calculations.

That's because bc uses base-10 arithmetic internally. It is the equal and
opposite phenomenon to the loss of significance in other languages when
using standard base-2 floating point.
