While checking my TH3D object, I found something strange.
Its number of the bin was 2, 6, and 4 respectively for x, y, and z axis.
root  myhisto->GetNbinsX() (int) 2 root  myhisto->GetNbinsY() (int) 6 root  myhisto->GetNbinsZ() (int) 4
But when I tried to get the content of the bin which is out of range, I got a nonzero value.
root  myhisto->GetBinContent(1,1,1999999999) (double) 1.0000000
which I expected to be zero.
I think it’s not normal, or is it?
I’d like to know what makes this situation.
