class MainClass

   static void Main()
   {
      Console.WriteLine("0.0f % 1.3f is {0}", 0.0f % 1.3f);
      Console.WriteLine("0.3f % 1.3f is {0}", 0.3f % 1.3f);
      Console.WriteLine("1.0f % 1.3f is {0}", 1.0f % 1.3f);
      Console.WriteLine("1.3f % 1.3f is {0}", 1.3f % 1.3f);
      Console.WriteLine("2.0f % 1.3f is {0}", 2.0f % 1.3f);
      Console.WriteLine("2.3f % 1.3f is {0}", 2.3f % 1.3f);
   }
}

0.0f % 1.3f is 0
0.3f % 1.3f is 0.3
1.0f % 1.3f is 1
1.3f % 1.3f is 0
2.0f % 1.3f is 0.7
2.3f % 1.3f is 1
