Windows Calculator Improvements

Windows Calculator has been updated (version 10.1803.711.0) to now correctly calculates square roots for perfect squares (integers that are squares of other integers). Because of the arbitrary precision arithmetic library used by the Calculator app, the square root calculation is an approximation calculated using the Exponential Identity function.

Previously, when you would calculate the square root of 4, the result would be 1.99999999999999999989317180305609 which would be rounded to 2 when displayed, because we calculated enough digits to do the rounding correctly. However, as soon as you subtract 2, you would see the remaining digits.

After this update, the square root calculation now recognizes perfect squares and correctly returns exactly 2 for the square root of 4.

Thanks. So I'd guess this would work with any perfect square? As in, sqrt(16) - 4. I wonder if cube roots were the same way. Like rt3(8) - 2. (I don't think it even had that functionality anyways...

As in, `sqrt(16) - 4`.

I wonder if cube roots were the same way. Like `rt3(8) - 2`. (I don't think it even had that functionality anyways though? At least not in the simplified view.)

I still had the vm lying around, so I verified for 6251/4 - 5 and 271/3 - 3, similar "almost zero" results.

This story was the first thing that came to my mind when I saw the other day's XKCD.

It happened in the 90s, I didn't read it right!

It's from 2002! I honestly expected such weird problems to be 90s or even 80s era internet growing pains. But it happened this millennium.

Ah, just read the date of the email! 90s makes more sense!
