Although it might be quite usual for people to find bugs, I think it's
quite unusual to have this kind of weird floating point error,
especially in standard double-float arithmetic which is provided by
the underlying lisp.
I suggest for your purposes to use SBCL or GCL, I think they are both
more likely to compile float arithmetic directly to machine code. Then
you'll only have to look out for hardware bugs similar to the original
pentium floating point division bug... :-)
