Interesting. The forum software appears to be rounding down to the nearest percentage in all cases. Perhaps they felt that it's better to err on the low side than risk getting a poll where they add up to over 100%, which would be possible with ordinary rounding.
Say we had real percentages:
A: 0.6%
B: 0.6%
C: 98.8%
=100%
Ordinarily that'd be rounded to:
A: 1%
B: 1%
C: 99%
=101%
As the forum does it I think it'd come out as:
A: 0%
B: 0%
C: 98%
=98%
In the best case, where there all poll response percentages are integers we'll get 100% but in any other case it'll come out less.
I think it's an emotive thing; they're working on the principle that people are happier with a less accurate rounding that returns a low total than with the awful, shocking, impossible, staggering idea of the percentage going over 100%. ^^
