Wolfgang, answer is not so much, in fact, not at all. But it is an interesting question for me; where I am continuing to learn the limits of Decimal, and the decimal context. I don't need rounding for integer multiplication, of course. I am interested in arbitrary limits, like emax, for instance. The doc is a little ambiguous. Is emax the max exponent, and if so, is 999999999 the limit, or is that the default context value which might be bumped up? If so, why have a limit on the emin & emax values? I'm playing with it. Shouldn't a Decimal value be able to continue to grow to the limit of memory if we wanted to be silly about it? According to the doc 'clamping' occurs if the exponent falls outside the range of emin & emax (what is overflow vs clamping ?) if the significant digits are allowed to grow and grow? Well, the doc then states that overflow occurs if we blow past the emax exponent value? What is the difference between overflow and clamping? Am I able to set emin & emax arbitrarily high or low? I have discovered just by playing with integer multiplication that those BIGNUMS don't seem to have a physical limit. Of course there isn't a decimal to keep track of, and they can just grow and grow; wouldn't want to make a Decimal from one of those, other than it is interesting to me as I'm trying to understand Decimal floating point. marcus -- https://mail.python.org/mailman/listinfo/python-list
