Old pentium bug still alive?
Found this in a public register in Denmark which lists who owns houses and apartments. This apartment is owned by 3 people each owning 1/3.

Looks fine to me.

Yes but it isn't 33.34 its 33.339999999999996 like the old pentium bug:

The Pentium bug's characteristics were different. As Nicely wrote in that famous memo, the Pentium bug showed up on calculations like 1/824633702441.0 They didn't cause (correctdigit1, followed by several 9's) errors. Last fiddled with by cheesehead on 20100408 at 16:56

Who needs 17 digits for that webpage anyway? With 17 digits you could individually number every square the size of ~ 40µm x 40µm over the entire Earth's land surface.

I think you got your maths wrong there. With 17 digits you can count to 10^{17}. The surface area of each is about 148,300,000 km^{2} . Let us round it to 1.5*10^{8} km^{2}. Now 1 km^{2} is 10^{6} m^{2}. So you get 1.5*10^{14} m^{2} = 1.5*10^{18} cm^{2}. So you get squares of cm^{2}. I think when you converted down from km^{2} you forgot to double the factor conversion.

148,000,000km^{2}
= ~ 12,000km x 12,000km = ~ 12,000,000m x 12,000,000m = ~ 300,000,000,000 (of 40µm) x 300,000,000,000 (of 40µm) = ~ 10^{23} (of 40µm)^{2} I don't know what happened there. Forget about the 40µm nonsense I posted above. Okay, so enough to count each 4cm x 4cm square. Thanks for the correction.

10^{23} / 10^{17} = One Million.
