Does anyone know how I use Rationals in ghc? In nhc I can just write
let a = b % c
But ghc-5.00.2 gives the error message "Variable not in scope: `%'"
I've looked through the documentation and can't find any reference to a
Rational library, or any other library that might have it. The package
"std" has a Ratio.hi in the lib/imports directory (std isn't described
in the documentation) but including this doesn't help - same error.
The Haskell98 report says:
"In particular, the type Rational is a ratio of two Integer values, as
defined in the Rational library."
