normal division x/y works just as expected, with one caveat: remember that if you divide two *integer* values, you will get an *integer* division operation yielding an *integer* result. So: 1.0 / 2.0 --> 0.5 1.0 / 2 --> 0.5 1 / 2.0 --> 0.5 1 / 2 --> 0 So if you make sure at least one operand is a real number you'll get a real result. This is now division works in many programming languages including C and C++. In the future, Python will switch to always yielding a real result, and to force an integer division operation you use the special "//" integer division operator. If you want that behavior now, just import that "from the future": from __future__ import division now: 1 / 2 --> 0.5 4 / 2 --> 2.0 1 // 2 --> 0 4 // 2 --> 2 HTH HAND >> from __future__ import division > > .. at the top of a module file.
