Comment:
I just added a patch which should fix this also. It does it in a slightly
different way. The sqrt() functions just are using the
is_square(root=True) functionality (one should not have two square root
finding algorithms in parralel). Also the sqrt() function has now the
optional parameter extend. The is_square() function now also uses the
trick mentioned by Peter the Bruin which is very general as it should be
in this general base class.
The patch should be installed aplied to 4.4.4 instead of the other patch.
