All numeric and enumeration types define a "greater than or equal" relational operator, >= that returns true if the first operand is greater than or equal to the second, false otherwise.
User-defined types can overload the >= operator. For more information, see operator. If >= is overloaded, <= must also be overloaded. Operations on integral types are generally allowed on enumeration.
class GTE { static void Main() { Console.WriteLine(1.1 >= 1); Console.WriteLine(1.1 >= 1.1); } } /* Output: True True */
