I've had Kraig Grady post a simple Excel spreadsheet that approximates intervals in cents by ratios by means of continued fractions at http://anaphoria.com/journal.html. It is based on a decimal to ratio converter written by Kardi Teknomo. Use Sheet 2 for your computations.

In additions to continued fraction convergents, the spreadsheet also computes string lengths and frequencies using several common pitch bases such as 440, 261.63, 256, and 264 hz.

I apologize in advance for cross-posting, but I think this program will be of interest to members of all three lists and will help limit future conflicts over representing scales in decimals, cents or ratios.
