Действительно ли желательно использовать платформы CSS?

Вот модифицированный код, который я использовал:

//Wrapper class for NumberToText(int n) to account for single zero parameter.
public static string ConvertToStringRepresentation(long number)
{
    string result = null;

    if (number == 0)
    {
        result = "Zero";
    }
    else
    {
        result = NumberToText(number);
    }

    return result;
}

//Modifications from original source:
//  Changed parameter type from int to long.
//  Changed labels to be singulars instead of plurals (Billions to Billion, Millions to Million, etc.).
private static string NumberToText(long n)
{
    if (n < 0)
        return "Minus " + NumberToText(-n);
    else if (n == 0)
        return "";
    else if (n <= 19)
        return new string[] {"One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", 
                                "Nine", "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", 
                                "Seventeen", "Eighteen", "Nineteen"}[n - 1] + " ";
    else if (n <= 99)
        return new string[] {"Twenty", "Thirty", "Forty", "Fifty", "Sixty", "Seventy", 
                                "Eighty", "Ninety"}[n / 10 - 2] + " " + NumberToText(n % 10);
    else if (n <= 199)
        return "One Hundred " + NumberToText(n % 100);
    else if (n <= 999)
        return NumberToText(n / 100) + "Hundred " + NumberToText(n % 100);
    else if (n <= 1999)
        return "One Thousand " + NumberToText(n % 1000);
    else if (n <= 999999)
        return NumberToText(n / 1000) + "Thousand " + NumberToText(n % 1000);
    else if (n <= 1999999)
        return "One Million " + NumberToText(n % 1000000);
    else if (n <= 999999999)
        return NumberToText(n / 1000000) + "Million " + NumberToText(n % 1000000);
    else if (n <= 1999999999)
        return "One Billion " + NumberToText(n % 1000000000);
    else
        return NumberToText(n / 1000000000) + "Billion " + NumberToText(n % 1000000000);
}
