Expand description

Recognizes a big endian 4 bytes floating point number.

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

    use nom::number::streaming::be_f32;

    let parser = |s| {
      be_f32::<_, (_, ErrorKind)>(s)
    };

    assert_eq!(parser(&[0x40, 0x29, 0x00, 0x00][..]), Ok((&b""[..], 2.640625)));
    assert_eq!(parser(&[0x01][..]), Err(Err::Incomplete(Needed::new(3))));
