Function recognize_float

pub fn recognize_float<T, E: ParseError<T>>(input: T) -> IResult<T, T, E>
where
    T: Slice<RangeFrom<usize>> + Slice<RangeTo<usize>> + Clone + Offset + InputIter + InputTakeAtPosition,
    <T as InputIter>::Item: AsChar,
    <T as InputTakeAtPosition>::Item: AsChar,

Recognizes floating point number in a byte string and returns the corresponding slice.

Complete version: Can parse until the end of input.
