this variable (believed to be an arry)... iNew divids equal to sum of all the values in iNew..
e.g.
iNew = {1,2,3,4,5}
so.. normal circumstands we can...
iNew / sum(iNew)
to become
{1/15, 2/15, 3/15, 4/15, 5/15}
However, if you are in a loop.. let's say 3 times..
a for loop{
iNew /= sum(iNew)
}
The /= means divides equal to
and
sum means adding all the values in that array.
