Computers can’t count
This one got pointed out to me from by Mike, so cheers.
As you can see from the screenshot above, as most will know Google has a inbuilt calculator so you bung in a sum and it returns the answer. However when you enter a 15 digit number – a 15 digit number it comes back with 0 (As shown above where 999 999 999 999 999 – 999 999 999 999 998 = 0).
Now firstly, this isn’t strictly speaking a Google error (although arguably they probably could fix it) it is infact cause is that the calculator program / operating system rounds the numbers causing the inaccuracy in the calculation.
For die hard geeks/maths nerds who want read more on why this happens you can take a look at an article on Digg.com which goes into this in detail and at time of writing has over 1200 diggs!
P.S Don’t forget to digg this post!
