Raymond:

The cleanups are OK.

Regarding changing == for =, didn't find nothing in the Spec
that says that after max() and min() you should *always*
round. So, I'll go for droping the line. But the tests are
OK with and without the assingment (IOW, with == and with
=), which makes me doubt.

I'm assigning this to you because I'm not sure about
commiting after beta.

Thanks!
