Oh, and @maynard:
Yes, I use Excel for personal finance and analysis purposes at home, and for various purposes at work when needed. So far, I have caught it making several mistakes, most notably the old "floating point error" that afflicted a lot of NT systems a few years back. In fact, I was the one who notified my credit union of the error, when evidence of it showed up on my bank statement. They were aghast.
As with ALL
software, trust but verify. That's why I have a 1980's Radio Shack "pocket" printing calculator in my desk drawer to check anything that has to be double-checked for calculation/data entry accuracy. ID10T errors are still the most common error type.
