Fixing a test failure in Py2.6

For some reason, win32 Python2.6 gives some array values that are off, like 0.1 --> 0.999999999999.  I seem to remember this happening all the time in the past, but maybe they changed something in Python 2.7. Anyway, the value of that array element is not important for this test. Regardless, I found a good workaround that preserves the spirit of the test.
