Nevermind I figured it out.
I used:
double costTwoDecimals = Math.Round(costTotal, 2);

public static string ToDecimalPlace(this double i, int decimalPlaces)
{
    string toString = i.ToString();
    int decimalPoint = 0;

    if ((i % 1) == 0) //Is the number whole?
        return toString;
    decimalPoint = toString.IndexOf('.');
    // + 1 takes account of the zero-based index returned by IndexOf
    return toString.Substring(0, decimalPoint + decimalPlaces + 1);
}

As far as I know, the framework doesn't provide this explicitly

public static double Truncate(this double d, int places)
    {
    double pow =  Math.Pow(10, places);
    return Math.Truncate(d * pow) / pow;

public class Localizer
