Thanks! For cdecimal specifically I have the impression that 3.x is already used in the financial community, where web framework dependencies aren't an issue. On the web side, there seems to be a huge interest in speeding up database accesses, so let me evangelize again: Database applications using decimal will run 12x faster in 3.3.

Are you sure it isn't 12.5x ?

Antoine.
