Talk:Introduction to functions

I made two small mistakes that I only noticed now. The sum of the arithmetic progression requires three variables to work with any sequence, not just 1 + 2 + ... + n. The function was defined as int, which means that if the result was non integer we would lose digits.

In the last algorithm the sum is an integer, but it's storing the result of a division of two integers. It's losing digits at each iteration. I also changed n from int to float because I think I confused the value of the variable with the value that the function returns.
