I'd expect this in gnc-numeric.c with a name like gnc_numeric_to_decimal or 
similar (like a class method).

On the first look it looks a bit weird, but on a second thought this is 
probably very useful. (This means the documentation should be very clear 
here.) Someone who wants a new gnc_numeric returned every time can easily add 
that as well as a second function. Looks good to me.
