simple implementation of mathematic function erf "Error function", in JavaScript JavaScriptによる誤差関数の実装
function erf(x){
// erf(x) = 2/sqrt(pi) * integrate(from=0, to=x, e^-(t^2) ) dt
// with using Taylor expansion,
// = 2/sqrt(pi) * sigma(n=0 to +inf, ((-1)^n * x^(2n+1))/(n! * (2n+1)))
// calculationg n=0 to 50 bellow (note that inside sigma equals x when n = 0, and 50 may be enough)
var m = 1.00;
var s = 1.00;
var sum = x * 1.0;
for(var i = 1; i < 50; i++){
m *= i;
