GenericOutStream<STREAMBUF>&
putFloat64(double value);Write to the stream supplied at construction the eight-byte IEEE double-precision floating-point number (in network byte order) comprised of the most-significant eight bytes of the specified value (in host byte order), and return a reference to this stream. If this stream is initially invalid, this operation has no effect. Note that for non-conforming platforms, this operation may be lossy.
