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

Streaming version: Will return Err(nom::Err::Incomplete(_)) if there is not enough data.

use nom::number::complete::float;

let parser = |s| {
  float(s)
};

assert_eq!(parser("11e-1"), Ok(("", 1.1)));
assert_eq!(parser("123E-02"), Ok(("", 1.23)));
assert_eq!(parser("123K-01"), Ok(("K-01", 123.0)));
assert_eq!(parser("abc"), Err(Err::Error(("abc", ErrorKind::Float))));
