paradox DOS used "banker's rounding".. round to the even side.. 5.5 rounds 
up to 6, but 4.5 rounds down to 4.. in theory, with large groups of numbers, 
that's more accurate, but it's not "normal"

from the beginning, paradox WIN used "banker's rounding, too, but I don't 
remember where it stopped.. only 16 bit BDE ??

Careful which rounding you use, and when:

5.5 + 7.5 + 6.5 + 9.5 = 29

After rounding: 6 + 8 + 7 + 10 = 31

9*42.45 = 292.905000000000000 (floating point)
Does x.round(292.905) become 292.90, or 292.91?

Exactly what are the rounding rules of p7/9.
Do currency and data type use different rule?

And finally..

A farmer counted 87 cows in the field, but when he rounded them up he had 
90.
