Comment(by maeder):
I've noticed the same problem for the float parsers in
`Text.ParserCombinators.Parsec.Token.exponent'` (or Text.Parsec.Token)
that use `10^e` to compute the factor. Using '10**e' instead (hopefully)
solved the problem in my `Text.ParserCombinators.Parsec.Number` module
(function `exponentValue`) from http://hackage.haskell.org/package/parsec-
numbers
