All you must do is to avoid decimal fraction because our computers
use binary fractions and truncate the number. Thus you may either
multiply each number by a factor large enough to get an integral
number and divide when you print/plot the results or you treat 0.2
as 1/5 and work on that. I guess this is what packages such as
Mathematica or Maple do.
