Contour, numbering contourlones

The attached MyContour.py generates ContourDemo.png (also attached).

My problem:

    The contours labels show 3 zeros beyond the decimal point. Is it
    possible to force these labels to integers? If so how? If not why not?

Ps.
    Is there a way to browse previous postings to matplotlib-users without looking month by month? For example can I bring up all postings regarding 'contour'?

thanks,

george
