Hi I understand 2%4 will construct a fraction in Haskell. I've tried this in GHCI but got an error message. Is there such an operator in Prelude and if so how is it applied? Cheers, Paul

It's not in the Prelude, it's in the Ratio module IIRC. Phil -- http://www.kantaka.co.uk/ .oOo. public key: http://www.kantaka.co.uk/gpg.txt
