# Is there a calculator out there that shows the full answer instead of shortening it?

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 $\sqrt{ 2 }$ ? – Mike Scott Feb 17 '11 at 14:23
• huh? you mean 4? – Pieter888 Feb 17 '11 at 14:26
• No, I mean 1.41421356..., continuing for ever without repeating. – Mike Scott Feb 17 '11 at 14:28
• Oh, alright. I'm not looking to calculate pi or 10/3. just some sums with very long answers. – Pieter888 Feb 17 '11 at 14:31
• Unix has bc for this, what does Windows have? – GEdgar Jun 1 '11 at 13:31

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:

10715086071862673209484250490600018105614048117055336074437503883703510511249361224931983788156958581275946729175531468251871452856923140435984577574698574803934567774824230985421074605062371141877954182153046474983581941267398767559165543946077062914571196477686542167660429831652624386837205668069376

• Thanks! That's exactly the kind of calculator I need :) – Pieter888 Feb 17 '11 at 14:32
• but even wolfram won't calculate Ack(5,5), so i guess it's a temporary solution :D – kneidell Feb 17 '11 at 14:36

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! – Pieter888 Feb 18 '11 at 11:42

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
