C# Example

using System;
using System.Globalization;
class Test {
 public static void Main() {
 NumberFormatInfo nfi = new NumberFormatInfo();
 decimal data = -.9900m;
 for (int i = 0; i<=2 ; i++) {
 nfi.PercentNegativePattern = i;
 Console.WriteLine("pattern # {0}: {1}",i,data.ToString("P",nfi));
 }
 }
}

The output is

pattern # 0: -99.00 %
