Karthik is correct, your GetRandomGaussian(double mean,double stddev) needs to return a double

}

What are you trying to do?
First, a method must have a return type (mark it as void, if nothing should be returned). Then you are trying to call a not existing overload of GetRandomGaussian, taking four arguments.
Finally you are using two sequential return statemets, the latter having NO effect.
What is your target? could you please describe it exactly?

Solution 1

add return type[^] to the method

public static double GetRandomGaussian(double mean, double stddev)
