Load into the specified `buffer` 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). The behavior is undefined unless `buffer` has sufficient capacity. Note that for non‐conforming platforms, this operation may be lossy.
