I'm trying to use function "errorfunction". when i use it like for calc probability integral like errorfunciton(i/sqrt(2)), i have values as probability integral 2/sqrt(2pi)*integral]0..x[(exp(-x^2/2). But in your description i see 2/sqrt(pi)*integral]0..x[(exp(-x^2). Where is error: you have foggoten 2 under square root, or tables are wrong?
Thank you.
