explode$ converts a string into Jess objects as if it were parsing
code; it turns floating point numbers into Jess "FLOAT"s, which are
internally just Java doubles. A Java double doesn't have this notion
of a fixed number of trailing zeroes (that's why they're
floating-point, not fixed-point.) So you can't really do this with
doubles in either Java or Jess.
What you'd have to do instead is keep them as Strings most of the
time. You can do that by double-quoting them -- i,e.,
Jess> (explode$ "\"2.000\" \"2.00\" \"2.0\"")
("2.000" "2.00" "2.0")
Note that Jess auto-converts Strings to numbers when it has to --
i.e.,
Jess> (+ "2.0" 3)
