Vector summation: ‘’’ sum([1/n^2 for n = 1:100000])‘’’ returns: 1.644924066898228 Generator summation: ‘’‘sum((1/n^2 for n = 1:100000))’‘’ returns: 1.6449240668982423 Why is there a difference in these results, and which summation method is the most accurate?

Why is there a difference when you Sum over an Array versus a Generator?
