putDoubleValue(
    std::streambuf* streamBuf,
    double value,
    xref:BloombergLP/balber/BerEncoderOptions.adoc[BerEncoderOptions] const* options = 0);
----

== Description

specified `streamBuf`. Optionally specify `options`, which will indicate whether `‐0.0` will be preserved or encoded as `+0.0`. Return 0 if successful, and a non‐zero value otherwise. The operation succeeds if all bytes corresponding to the length and contents octets are written to the `streamBuf` without the write position becoming unavailable.

== Return Value

0 on success, and a non‐zero value otherwise
