Constants not equal? - Brain Teaser

[craige]

So i'm plotting some data to an XY graph and expect to see a straight line but I don't. I copy the data from my VI and paste it into a "sandbox" so to speak just to play around. Check out the attached VI. Why does the left most graph not plot a straight line? Something tells me this has to be something with the display format and in fact these contants are not equal but I can't quite figure it out.

This is LV2010sp1.

Thanks,
Craig

Changing it by adding a 1 and removing it, thus only updating the number causes it to be equal on my computer. I have no idea why though.

Display a few more (e.g. 20) decimal digits and you see the difference.

Subtract the two clusters and you see that the difference is about 1.7E-14, but not always exactly the same.

Where does the data come from?

Why doesn't the constant autosize to show the full number?

Hi Yamaeda,

why should the indicator do so? You have to set the display format to the desired value...

Does somebody owe me another nickel in my retirement fund.?

That's two nickels this week. Pretty soon I won't need to win the lottery.
