Floating-point round-off problems.

Does anyone have a hack to correct for the losing floating-point math on
these Symbolics machines?
(- 6 5.9) returns -> 0.099999905 instead of 0.1
Have you considered using exact rational arithmetic instead of floating
(- 6 59/10)
If you don't like reading these, you can have your output routines
convert them to floating point just for displaying to the user:
(coerce (- 6 59/10) 'float)
