Obviously that should have read "are not stored".

Are you dealing with numeric or character variables?

You do realize that most fractions, such as .2 and .33 are stored as
exact numeric values in the computer.  If you specify a sufficient
precision, .2 will print as .19999999999968 or some such value depending
on how your hardware stores floating point values.  How do you intend to
distinguish between the two.
