Thread: Brain Burp Rounding??

To say "NO!" is a bit emphatic, since I could just as well say that we
will only truncate numbers, which would provide an answer which may be
fine for some conditions.

I understand your logic; but this is still including 500 numbers below
the "rounded to" value and 499 above, therefore (and I repeat)
statistically, you are favoring the round up when given a random set of

 Again looking at the results of the scenario I presented below,
The actual answer is                 2260 +/- 10

The "Round >=5" result is            2270  (+0/-20)
The "Round Even if 5" result is      2260  (+/- 10)
And the "Truncate" result is         2250  (+20/-0)

So which answer is right?
  All of them (or none of them) depending on the requirements...
