I've a feeling that, most of the real world requirements involving decimal
values is rounding of the value (as per function reference above), and not
truncation. Am I correct, please?
On StackOverflow this question would be instantly closed as one that attracts
opinions rather than facts. None of us know how to find out how many people in
the world prefer truncation to rounding (or whether they are right to have that
preference...). And it really doesn't matter how many people prefer one over
the other: if your client is subject to accountancy regulations that say how it
should be done, then that's what you have to do.
In the real world some quite complex rounding requirements arise, for example
rounding percentages so that they total 100.
