Is this Windows Calculator Bug ?

Just noticed one of the error in Windows Phone Calculator when performing an calculation …

Below are steps to reproduce this

1. Open the Windows Phone Calculator and switch to the LandScape view.

2. Enter the number 4 and tap Square root button . This will give the result 2.

3. Now subtract 2 from the above answer . What is the expected result ? Zero ? . You will get a different result as shown in the screenshot.

When trying the same on my Windows 7 Desktop too resulted in the same value …

Is that a Bug ? I think its a Kindoff Bug probably rounding error …

Got an update from @kunal2383 regarding this error . Here’s an article that describes the floating-point numbers. . Thanks Kunal ๐Ÿ™‚
