[Haskell-cafe] Parsec float

Hi Everybody (especially Parsec Creator), is there any reason why float parses only positive numbers? I find following defition: float = lexeme floating "float" floating = do{ n <- decimal ; fractExponent n } If floating was defined like floating = do{ n <- integer ... or floating = do{ n <- int ... instead then it would parse negative ones as well.
