The values are stored that way, instead of as a float, when they are
exact.

I'll add optional element to the `math-standard-units' entries that will
determine how to display the definition in the table, so the tsp
definition will be displayed as in the second case above.  (I don't want
to change the definition or have the table display all fractions as
floats, so I'll have Calc determine how to display the entry on a case
by case basis.)  Perhaps there should also be an indicator in the
displayed table telling whether the definition is exact or not.
