Not only will it fix the "overshooting" problem I mentioned a while back, but it has other desirable properties. (Naturally for use in ->Q the tolerance would be taken from the system settings and one wouldn't bother calculating the error. But the full-blown PDQ might make a worthy command in its own right.)

I like it! I hope Joe doesn't mind if his algorithm ends up being ported to newRPL, I'll make sure to provide proper attribution for the algorithm in the source code.

Great! Also, please consider exposing the "ISQR" and "CF~I2" commands to the user, they are of considerable interest. Though I'd recommend having the latter output a symbolic fraction rather than a pair of integers (and therefore changing its name to something like "QXCF".) The former might be more clear if named "ISQRT" too.
