I’m sure many of you are aware of the calculation function that Google Search Engine provides. For example, you can do simple math like : 2+2+193+213-21 (just type it in Google, and it will automatically do the math for you).

But recently ZDNet Australia reported that Google’s calculator has some serious trouble handling math that involves some large numbers.

For instance, 2,999,999,999,999,999 minus 2,999,999,999,999,998 should be 1, but Google calculator shows it as zero.

Normal hand held calculators usually run out of steam when trying to calculate big numbers. Sure, Google may have some issues, but most ordinary calculators don’t even let you type the number 1,999,999,999,999,999 much less do some mathematical operation on it. And there’s not any substantial market for software such as Wolfram Research’s Mathematica that can do that kind of math right.

Google acknowledged that their math calculation is imperfect. They said:

“We are aware that the calculator tool in Google Web search is not working properly for certain calculations, and we are looking into this problem further. We apologize for any problems that this causes our users”

Some other users have found limitation with Google’s calculator. For Instance, 2.00135558564^1023 is interpreted by Google’s calculator as 1.79769313 x 10^308. But if you increase that number by a little amount to say 2.00135558565^1023, Google starts interpreting the math problem as a search query.

Good post just goes to show that Google is also wrong some times.
