Hi,
In
https://github.com/SOCI/soci/commit/57704504bfd4f5aec5fe0db1ea596d2613db746dI'm
trying to check for infinity and NaN and throw a soci_error if that's
the case. The solution may not work for non-IEEE-754 implementations, in
particular for g++ --fast-math, but I know of no better way of doing it
portably in C++. In C++11 there is a special function for that,
std::isfinite(), which we should start using once we're in the C++11 world.
Let me know if this solution is satisfactory for you.
Thanks,
Aleksander
