Re[2]: [Haskell-cafe] Fortran mixed mode arithmetic expressions -> Haskell

Hi Brandon,

Being new to Haskell, I take it (^) and (^^) would be the preferred exponential "operator." When (how,where,why) would one use (**)?

It's correct if perhaps not ideal for someone who doesn't think in terms of Haskell.  (**) is a member of a typeclass, whereas (^^) is an independent function; you are expected to check that the typeclass is appropriate for what you're doing.
