Re: MySQL: implicit float cast different between 32bit and 64bit mysql-version

Matthias, was that on the same hardware and OS?

Jon, a third if a century ago, the IEEE-754 standard mostly obliterated the incompatibility of FLOAT and DOUBLE. Could it be that the conversion library has changed? Could it be that MySQL used to treat that as DECIMAL, not does it as DOUBLE? (Or vice versa) Perhaps the 32-bit library does not adequately emulate 64-bit arithmetic?

On the one hand I defend MySQL's caveat; on the other hand I smell a software bug somewhere.
