The excel executes user code, user code executes system code, system code runs floating-point calculation on the processor, floating-point calculation is done with discrete mathematical algorithm and discrete mathematical algorithms are not exact.
This seems does not worry the financiers, since they always use rounded to 2-4 digits (after point) result.

Finances will be fine, most of the companies don't use more tan two digits (so this will be rounded to zero), and even the most picky ones don't use more than 10.

Don't you just love floating point rounding? I lost track of the number of VB6 "bug" blogs that were nothing more than floating point rounding issues.

Nah...
It is people that cause problems.
Out of all the programs that I use, it is probably Excel that is the one that I wish that I wrote.
It is sensational.
I can still output old biff file format and Excel will recognise and open it immediately.
Give any user a great and powerful application and of course they can cause havoc and hell.
Its the way things are and always have been.
...and Yep I have also elephanted up a spreadsheet and was horrified by my error or errors.
But Hey... How good is it.

I don't know about the USA, but in the EU - all financial calculations must be performed in DECIMAL arithmetic with a specific accuracy (IIRC, 5 digits after the decimal point). Rounding is also performed using a specific algorithm (IIRC - rounding after conversions from legacy currencies had to be performed as "round to nearest or away from zero").
Excel's calculation method does not satisfy any of these requirements, so no large company based in the EU would use Excel for record keeping.
I grant you that when programming financial models, rounding errors can accumulate catastrophically and give totally bogus results. The first part of the solution to this is a good course in Numerical Analysis...

So...I'm just guessing that the whole of Iran won't be hungover tomorrow?

One implies a limitation, Chuck has no such limitation, he just knows.

At 12:57PM EST, I for one am glad to see it here. This winter has been the worst I can remember for many years and I've gained 15lbs and feel like a sloth. Today is going to reach 73F here in SC and I am going to get my lazy butt out for a hike in preparation for my upcoming trip.
Happy spring y'all!

We've just had 4 days of 40-50F days of rain, cloudy and just crappy weather, I am so ready to get out of the house.
