2016-04-11 Thread Aaron Meurer
It's worth pointing out that if you use exact integers or rationals (you can convert a float to a rational with nsimplify()), then there are no accuracy loss issues, because the result of the calculation will be a (large) rational number, which can be evaluated to a float exactly. Also, if you are

Very Large number Calculations with No Loss in Accuracy ? Given a 1700 digit number, we want to store the value and perform two functions on it with NO loss of accuracy, its ok if calc time takes longer but better if faster. Where x = a 1700 digit long numeric value The two calcs to be compute
