Microsoft Calculator #FAIL

Windows calculator is an essential tool . No doubt that it is simple and efficient piece of software. Today I came across a video mentioning about bug in simple calculation. The error is reflected in all versions of Windows( I believe ). Tested with Windows 7 and XP. Both of them showed the error.

Don’t get excited feeling that it is BIG ONE.

  • Enter 4 and find square root using the Sqrt button.
  • You will get the result as 2
  • Subtract with 2 and see the final result :)

  1. What a failure on Microsofts part. It’s amazing how they can design an entire operating system and then mess up something as simple as a calculator.
