# 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 ?
