pub fn be_f32<I, E: ParseError<I>, const STREAMING: bool>(

Expand description
Recognizes a big endian 4 bytes floating point number.
Complete version: Returns an error if there is not enough input data.
Streaming version: Will return Err(nom8::Err::Incomplete(_))
if there is not enough data.
Example
use nom8::number::be_f32;
let parser = |s| {
be_f32(s)
};
assert_eq!(parser(&[0x41, 0x48, 0x00, 0x00][..]), Ok((&b""[..], 12.5)));
assert_eq!(parser(&b"abc"[..]), Err(Err::Error((&b"abc"[..], ErrorKind::Eof))));
use nom8::number::be_f32;
let parser = |s| {
be_f32::<_, (_, ErrorKind), true>(s)
};
assert_eq!(parser(Streaming(&[0x40, 0x29, 0x00, 0x00][..])), Ok((Streaming(&b""[..]), 2.640625)));
assert_eq!(parser(Streaming(&[0x01][..])), Err(Err::Incomplete(Needed::new(3))));
