Expand description

Recognizes a big endian 8 bytes floating point number.

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

let parser = |s| {
  be_f64::<_, (_, ErrorKind)>(s)
};

assert_eq!(parser(&[0x40, 0x29, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00][..]), Ok((&b""[..], 12.5)));
assert_eq!(parser(&[0x01][..]), Err(Err::Incomplete(Needed::new(7))));
