My issue is that this is a ridiculous issue to bring up in an MPSIMS thread.
Your opinion.
But I will note that I broke it off to bring it to GD, you did not.
Precisely 50% is clearly not a majority: that would be, at best, a draw. Therefore you need more than half: if N is the total number of votes and a is the number you need, we have
a > \frac{N}{2}.
Nothing fancy means that a must be an integer. In that case, we can strengthen the above inequality to
a > \left\lfloor\frac{N}{2}\right\rfloor.
That means the smallest number of votes that works is \lfloor N/2\rfloor+1, so the “+1 stuff” is merely a reformulation, not saying anything different to “more than half”.
And assuming whole votes sure. But the 50%+1 crowd do not use the floor function in their definition.
Closed for review, too many flags coming in.
I spoke to Saint_Cad, we agreed, we’ll leave this closed.
