I couldn't find anything for regular python on the fly (except by using the "decimal" module, see http://docs.python.org/library/decimal.html#module-decimal), but I found out that IPython can do this by configuring its output formatters appropriately. To limit to 6 decimal places, my configuration would look like this: c.PlainTextFormatter.float_precision = '6' I would expect that all they do is implement hook functions that you could also put in place yourself, but to find out how to do it would require more digging than I have time for right now. Maybe you will find something first :) . HTH -- Marc Joliet -- "People who think they know everything really annoy those of us who know we don't" - Bjarne Stroustrup
