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.apache.org/xmlrpc/advanced.html
The feature was specifically developed with topics like that in mind.

> Priority: Critical

> 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
