Function nom::double

pub fn double<T>(input: T) -> IResult<T, f64, u32> where
    T: Slice<Range<usize>> + Slice<RangeFrom<usize>> + Slice<RangeTo<usize>>,
    T: Clone + Offset,
    T: InputIter + InputLength + ParseTo<f64> + AtEof,
    <T as InputIter>::Item: AsChar,
    T: InputTakeAtPosition,
    <T as InputTakeAtPosition>::Item: AsChar, 

Recognizes floating point number in a byte string and returns a f64
