Add predicates returning if the scientific is floating or integer #17

This would be useful when we need to make decision only based on whether the scientific it's floating point or integer. Especially when warn-type-defaults is on, we can write

  if isFloating s then d else i

instead of

  either (const d) (const i) (floatingOrInteger s :: Either Double Integer)

or

  case floatingOrInteger s of
    Left (_ :: Double) -> d
    Right (_ :: Integer) -> i

Thanks for the patch!

These will be included in the next release.
