Python 2.x defaults to integer division, a design error which has been rectified in 3.x. One can do any of these: [st...@sylar ~]$ python3.1 -c "print(1/2 * 1/2)" 0.25 [st...@sylar ~]$ python2.6 -c "from __future__ import division; print 1/2 * 1/2" 0.25 [st...@sylar ~]$ python2.6 -Q new -c "print 1/2 * 1/2" 0.25 [st...@sylar ~]$ python2.6 -c "print 0.5 * 0.5" 0.25 and probably many others as well. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
