   Isn't the problem that 22.22 cannot be represented exactly in binary
   floating point, thus is subject to various rounding issues in the
   least significant digits?  Perhaps using values like 22.5, 22.25,
   22.125, etc. would eliminate these problems.

 Doh!  I should've thought of that!  Yes, that does give better
 results, and the author of those tests, who is on this list, says
 "change 'em however you want".  So that's what will happen.  Thanks! -s
