I'm looking for a calculator that shows a full answer regardless of it's length.

For example the assignment 2^1000 will output: 1,07150860718626732094842504906e+301. Windows calculator shows me that amount because else it won't fit the display.

So the question is: Is there a calculator out there that shows the full answer instead of shortening it?

    What do you expect this hypothetical calculator to display when you enter $\sqrt{ 2 }$ ?2011-02-17

    No, I mean 1.41421356..., continuing for ever without repeating.2011-02-17

    Oh, alright. I'm not looking to calculate pi or 10/3. just some sums with very long answers.2011-02-17

    What you want is not usually called a "calculator" but a "computer algebra system".2011-02-17

    Unix has bc for this, what does Windows have?2011-06-01

    There certainly are *calculators* with such functionality. The HP49/50 series supports arbitrary precision integer arithmetic, and I computed $2^{1000}$ without trouble. I believe the TI89 series has this as well, but I am not sure.2011-06-01

    wxMaxima and DrRacket are 2 more options, I use both, but they are both more-than-a-calculator.2014-04-29

If you don't mind a web-based solution, wolframalpha.com will do that for you:

http://www.wolframalpha.com/input/?i=2^1000 

outputs:

    Thanks! That's exactly the kind of calculator I need :)2011-02-17

    but even wolfram won't calculate Ack(5,5), so i guess it's a temporary solution :D2011-02-17

Have a look at this site: it is dedicated to large number factorizations, but you can also make some integer based operations. You can input "2^1000" and try.

    Also a nice one. thanks!2011-02-18

You can also consider Maple, and Pari-GP.

Of course not. Any computer (e.g. calculator) has finite memory, so there will always be numbers that are too long to display fully.

Wims Function Calculator also gives 10715086071862673209484250490600018105614048117055336074437503883703510511249361224931983788156958581275946729175531468251871452856923140435984577574698574803934567774824230985421074605062371141877954182153046474983581941267398767559165543946077062914571196477686542167660429831652624386837205668069376.

You can try Python console. Python can work with large numbers, and you can use it as calculator
