    e times pi...hmmm

    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.

    Thanks

    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.

    You need an extended precission tool such as built into Mathematica, Derive, ..
    Unfortunatly this is not my computer and I don't have my tool set installed here.

    Ok, thanks for the swift reply.

    Do you know where i could get such software. As an alternative, do you think you could do the sum on your own computer and post the reply.

    Thanks a lot

    The two quoted are comercial, ubasic will do the job and is free, as is yacas

    (Google for them)

    by the way, Derive gives:

    e^pi ~= 23.14069263277926900572908636794854738026610624260 0
