Oh sorry! I felt all speacial.  But I doo have a suggestion, why don't you
enter the decimal as a string then find the length , convert the string
to I guess a double and then multiply it by a power of ten to make it an
integer. Then use the integer and the power of ten as you numerator and
denominator and then use the code I gave you or whatever.  Oh and by the
way count down not up I made that mistake myself.
