Hello, i checked, and i can say that

• a goroslib service provider can read a float64 NaN sent by a C++ service client
• a goroslib service client can read a float64 NaN sent by a C++ service provider

Regarding JSON (that is not related to this library), it doesn't support NaN or infinity, according to the specification (see here https://stackoverflow.com/questions/13581843/php-how-to-encode-infinity-or-nan-numbers-to-json).

@aler9 I misread the log before. This error is the error that I used the log framework to print the structure.
