Function float

pub fn float<T, E>(input: T) -> Result<(T, f32), Err<E>>
where
    E: ParseError<T>,
    T: Clone + Offset + ParseTo<f32> + Compare<&'static str> + Input + AsBytes + for<'a> Compare<&'a [u8]>,
    <T as Input>::Item: AsChar,
    <T as Input>::Iter: Clone,

Recognizes floating point number in text format and returns a f32.

Complete version: Can parse until the end of input.
