Logarithms

I've tried looking on the net with no luck. I'm developing a small program for a pocket PC using C# MSVS 2005. I want to use the math routine log but It doesn't recognize "log" or "Log". How do I go about calculating the logarithm of a number to any base? There's got to be a routine built in for that. Thanks

you mean like this

Code:

---

using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            double x = 0.5;

            double y = Math.Log(x);
            Console.WriteLine(y.ToString());
        }
    }
}
