Is This the Most Silly Bug in Microsoft Windows Calculator ? 2-2 != 0
The windows seven calculator is way cooler its previous versions. But it has this same calculation bug it had earlier. If you subtract 2 from the square root of 4 then the result is not 0 but -1.068281969439142e-19. Interesting is previously in windows XP the result was -8.1648465955514287168521180122928e-39. So that’s an update in Seven right ?
Silly Bug in Microsoft Windows Calculator ? 2-2 != 0 ?
Step 1 : Open Windows Calculator.
Step 2 : Press the number 4 and apply Square root which gives result 2.
Step 3 : Now subtract 2 from the answer ie, 2-2 and press equals [=]
Shocking bug right ?
I learned that 2 – 2 = 0 but windows calculator has some different suggestion. Watch the demo below

Shiva | Web Magazine : I hope it is some kind of an easter egg
Tiny Tim : Weird. When I do it, I get -8.1648465955514287168521180122928e-39
Debajyoti Das : @Tiny Tim: Its becoz you have XP or Vista
stuart : i like "2+2*2" in scientific mode it gives 6 , in standard mode it gives 8
Herald Friday : Basically, it's just arounding error. The square root of 4 is, according to the computer 1.9999999999999999999 ad infinitum, but it runs out of digits. It then shows it as 2, and then when you subtact 2 from that, you get the result of 0.00000000000000000001, or -1.0 ^ -19 as is shown here. Yeah, I simplified it a bit, and it is technically a bug, but it's a relatively small one. Different number of digits available = different results in different versions of Calculator.
windows 7 serial : I’m gone to tell my little brother, that he should also go to see this website on regular basis to get updated from most recent information.
Gumshoe009 : There is even a more bizarre bug in calculator: 1000 + 40 + 1000 + 30 + 1000 + 20 + 1000 + 10 = 4100 (not the correct answer, 5000).
