All numeric and enumeration types define a "less than" relational operator (<) that returns true if the first operand is less than the second, false otherwise.
User-defined types can overload the < operator (see operator). If < is overloaded, > must also be overloaded.
using System; class Test { public static void Main() { Console.WriteLine(1 < 1.1); Console.WriteLine(1.1 < 1.1); } }
