Ok, ive come up against a maths puzzle which requires me to find out the answer to e^pi to at least 40 decimal places. I have no idea how to find these dps because my calculator wont go that far. I heard someone mention something about long multiplication but im not sure. Any help would be greatly appreciated.
P.S if anyone is wondering, the puzzle includes using certain numbers specified by their decimal place (ie a = 23 decimal place) for another part of the puzzle.
