E.g.: Linux: "nan", > Solaris: "NaN", AIX: "NaNQ" > After I sent it and reread my mail, I realized that my fix wouldn't be enough because of the above: ECPG uses sprintf() for float and double, and just like in the backend, a common code to send "NaN" and +/- "Infinity" to the server is needed. New patch is attached. Best regards, Zoltán Böszörményi -- Bible has answers for everything.
