:mrdocs:

Write an array of eight‐byte IEEE double‐precision values to this stream.

== Synopsis

Declared in `<bslx_genericoutstream.h>`

xref:BloombergLP/bslx/GenericOutStream.adoc[GenericOutStream<STREAMBUF>]&
putArrayFloat64(
    double const* values,
    int numValues);
----

== Description

Write to the stream supplied at construction the consecutive eight‐byte IEEE double‐precision floating‐point numbers (in network byte order) comprised of the most‐significant eight bytes of each of the specified `numValues` leading entries in the specified `values` (in host byte order), and return a reference to this stream. If this stream is initially invalid, this operation has no effect. The behavior is undefined unless `0 <= numValues` and `values` has sufficient contents. Note that for non‐conforming platforms, this operation may be lossy.

== Return Value

a reference to this stream

== Parameters
