In what sense is this a bug or misfeature?  the gnc-numeric API just
provides the mechanism to do the math; the calling code specifies if it
wants to have the denominator automatically computed or not.

Don't forget that the denominator you supply can be GNC_DENOM_AUTO, in
which case you have several options as to how to automatically compute
the denominator. 

The *_fixed API is a convenience for the case of collecting currency
values; it *is* an error to try to use different denominators in some
cases. If that's not the situation that you are in, then use the general
API and don't specify the flags that cause errors to be raised on
different denominators.  

b.g.
