2002-02-12 I had forgotten, but I have a calculator than can do fractional math. It is a Casio fx-911D Scientific Calculator. I played with it for a while and I must admit, it is very complex and time consuming to do the numeric entries. It does not force results to binary fractions. If you add 1-3/4 to 3-3/5, you get 7-7/20. You can even press a button to convert it to 107/20.
If you add a decimal to a fraction, the result is a decimal. There is suppose to be a way to convert fractions to decimals and back, but since I lose the manual, I don't know how to do it. I don't know if this calculator qualifies as the type Marcus is referring to. John ----- Original Message ----- From: "James R.

The important thing is that noone has come up with a binary fraction converter yet. *That* is a relief... On the other hand I still don't like seeing decimalizations of ifp units. To me that poses as a bigger threat to the acceptance of SI in the US than many other things, especially considering that the rest of the world could probably "accept/tolerate" them more than if they came in the usual crappy fractional way... > > I have seen handheld electronic converters (calculators) that are > advertised as converting between SI and fractional inches, feet and > inches, and so forth.
