Function recognize_float

pub fn recognize_float<T, E: ParseError<T>>() -> impl Parser<T, Output = T, Error = E>
where
    T: Clone + Offset + Input,
    <T as Input>::Item: AsChar,

Recognizes a floating point number in text format and returns the corresponding part of the input.

Streaming version: Will return Err(nom::Err::Incomplete(_)) if it reaches the end of input.

  recognize_float().parse(s)
