Just visited the GO homepage for the first time. I saw the operational examples list and tried a couple of them.
I tried the “Concurrent Pi” example and the result was Pi = 3.1417926135957934
Pi is 3.14159265358979323. Did I miss something?
I am new to the GO programming language and know only what I’ve learned from the video on the webpage.

The sample code is an approximation of pi, I imaging if you increase the number of iterations (hence goroutines) to 10,000 or 20,000 the result would converge closer to the real value of pi.
