I haen't looked at the code in question closely, but the problem here
may be that (= x 0.0) is rarely likely to be true, even when you think
it should be. In particular, it will be false, even if x is *very*
close to zero (i.e. (set! x 0.00000000000001)). In most cases, we
should probably have a gnc:financially-zero? predicate, or something
like it (with a better name) that checks to see if a value is small
enough to be considered zero in cases where exactly zero isn't what's
intended.
