Well, I'm an engineer rather than a mathematician, so I'm not 100% sure I followed everything on that page, but you seem to be saying that nth-root can't be done because we're using floating point, and floating point isn't accurate enough to represent 1/n.
Yes that's one problem.
I basically agree with this, which was why I asked about nth-root functions, but for my uses (**) is good enough as long as complex zero works.
In NumericPrelude we have the 'root' function for that purpose. _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
