[−][src]Function nom::number::streaming::be_f64

pub fn be_f64<I, E: ParseError<I>>(input: I) -> IResult<I, f64, E> where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength,

Recognizes a big endian 8 bytes floating point number.

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