If you enter the expression in exact mode, with all the numbers being integers (no decimal point!), and EVAL it instead of using >NUM, then you'll get the exact answer 4117367101025. Ditto for any upper limit or power (within reason of course!). If you are in exact mode, but still get floatingpoint approximations instead of exact integer results, your flag 3 might be set, or some other flag.

I found a post mentioning the library longFloat (how much great work on for those little devices!) but before trying to use it I would like to ask here, where there are a lot of experienced people compared to me. It can output integers of any length, but floatingpoint precision is always 12 mantissa digits unless you insteall the LongFloat library, which you should, because it's awesome, allowing mantisssas up to 9999 digits long(!), and huge exponents. <0ΙΈ0> Joe
