When comparing a given value with a database of values, but allowing for freedom due to variation at say, the thousandth digit, how does one generalize the precision to this degree? I don't want to truncate, so is there a round() function that takes into account what decimal place the value (database value) needs to be rounded to?
Thousandth digit??? Python doesn't support floating point numbers with a thousand digits! I think about seventeen is about the limit.
Yes, there is a round function: >>> x = 123.45678 >>> y = 123.45731 >>> x == y False >>> round(x, 3) == round(y, 3) True -- Steven _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
