Windows 8 Calculator Incapable of Handling 64 Bit Numbers


  • I find it incredible that Microsoft still has not fixed the limitation with the Calculator application that they introduced in Windows 7.

    Hasn't anyone ever tried to manipulate large unsigned 64 bit numbers with it?

    Set it to Programmer mode and try entering the number 10376293541461622784, which is 0x9000000000000000 (hex).  You won't be able to get the last digit in.  If you switch to hex and enter 9000000000000000, you'll find it to be a negative number after a switch to decimal.

    The old XP calculator was more capable (and thankfully still works in Windows 8 CP).

    Yes, the limitation of Programmer mode calculator still exist on Windows 8. That seem a by design behavior. Also I will help to you submit this symptom, I believe it will improved in the feature.

    Thank you for your understanding.
