I'll point out that floating-point vs. BCD or something like it is SO
not an issue with the real-world financial calculations the SEC is
worried about.  (Well, it is an issue for the calculations, but it is
not an issue for the people doing them.)  Most everyone in that
community has long accepted binary floating-point as completely adequate
for doing financial calculations for complex products.
