One more reason to quit Windows ...

**banskt** · November 3rd, 2010

Hi all,

Today I stumbled to find a strange bug in the windows calculator. A google search just told me that this bug is well existent...

But I think its the most awful error of Microsoft. It shows 0 = 4.74665 ...

Actually, windows calculator fails to do the "square root" operation properly.

We all know that,

$\sqrt{(10^{37})^2} - 10^{37} = 0$

if you do the same in windows calculator (do the square root and then, subtract) you will find,

$\sqrt{(10^{37})^2} - 10^{37} = 4.7466522942022786223711731575919$

Using translative property (if a=b, and a=c, then b=c), one sees that

$0 = 4.7466522942022786223711731575919$

Note that we have not used any undefined operations here.

This is a known bug, and I googled to find a youtube video.

To be noted here is that Linux does not produce this bug.
Quit Windows, use Linux ...
