Google calculator gives answer 0 where as duckduckgo calculator answers with 2. xD

  Bing gives 1 though!

    So duckduckgo uses the normal 64bit floating point, and the clever people at bing automatically switch to bignums when needed. But I have no idea what google does to get that 0?

      I think Google is truncating the numbers. You get 0 even if you do: 9999999999999999 – 9999999999999990

        9999999999999999 - 9999999999999971 == 0 9999999999999999 - 9999999999999970 == 30 9999999999999999 - 9999999999999969 == 32 9999999999999999 - 9999999999999966 == 34

  That's disappointing. The Android calculator has an awesome arbitrary precision engine (implemented by Hans Boehm!). https://cacm.acm.org/magazines/2017/8/219594-small-data-computing/fulltext https://cacm.acm.org/magazines/2017/8/219594-small-data-comp...

  Interesting thing is that Google calculator will give 2 if you fill in the numbers by clicking on the calculator buttons, instead of writing them in the search bar.
