Dear all,

I am new here.

I try to calculate the following:

∑ (1/X, X, 1, 10) and I get the answer 7381/2520, which is roughly 2.92 after manually dividing the two numbers in the fraction.

When I try to calculate ∑ (1/X, X, 1, 100), the answer is a very long fraction that doesn't even fit on one screen.

Is there any way to show the answer as a decimal number instead of a rational number?

My bad. After reading the manual I've found the solution to my problem. Just add "approx" in front of the expression. The answer will be a decimal number.
