Is there a formula, extension, or something in calc that enables one to calculate the sum of 1..N, where N is an integer between 0 and 100 000 000?
Yes. Sigma (1 to n) is n(n+1)/2.
If so, what is the formula, extension, or something?
=Xn*(Xn+1)/2 I trust this helps. Brian Barker --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
