Re: Program to calculate rational function with imbedded continued fraction

Hi Diana,
the function "FromContinuedFraction" will convert a countinued fraction 
into a "ordinary" number representation. You can then use this number in 
your formula. Of course this will only work if the infinite continued 
fraction is periodic (or terminates, but then it is not infinite). 
Otherwise, you can not represent the number in a form 
"FromContinuedFraction" will swallow.
