Jochen Wiedmann closed XMLRPC-146.
----------------------------------
Resolution: Won't Fix
The value "nan" is definitely a violation of the
XML-RPC specification. In other words, this cannot be
supported by an XML-RPC compliant implementation out of the
box.
Apart from that, as far as I know, you're the first one who
requests that after quite some years of XML-RPC. In other
words, I doubt that the feature is sufficiently common to
justify inclusion into the core code. Therefore, I'd ask you
to use a custom type factory, as described in
http://ws.a
pache.org/xmlrpc/advanced.html
The feature was specifically developed with topics like that
in mind.

> I got an XML-RPC remote server (EPICS archiver) written
in C++. I have no way to change code / version etc on this
server. This server returns timestamped doubles by the
request of my Apache XML-RPC clients. It returns Not a
Number (NaN) as string 'nan'. That causes an parsing
exception in Apache XML-RPC library:
> org.apache.xmlrpc.client.XmlRpcClientException: Failed
to parse servers response: Failed to parse double value:
nan
