All numeric and enumeration types define a "greater than" relational operator (>) that returns true if the first operand is greater than the second, false otherwise.
User-defined types can overload the > operator (see operator). If > is overloaded, < must also be overloaded. When a binary operator is overloaded, the corresponding assignment operator, if any, is also implicitly overloaded.
static void Main()
Console.WriteLine(1.1 > 1);
Console.WriteLine(1.1 > 1.1);
