/ Operator (C# Reference)
Visual Studio 2010
The division operator (/) divides its first operand by its second. All numeric types have predefined division operators.
User-defined types can overload the / operator (see operator). An overload of the / operator implicitly overloads the /= operator.
When you divide two integers, the result is always an integer. For example, the result of 7 / 3 is 2. To determine the remainder of 7 / 3, use the remainder operator (%). To obtain a quotient as a rational number or fraction, give the dividend or divisor type float or type double. You can do this implicitly by expressing the dividend or divisor as a decimal by putting a digit to the right of the decimal point, as the following example shows.
class Division { static void Main() { Console.WriteLine("\nDividing 7 by 3."); // Integer quotient is 2, remainder is 1. Console.WriteLine("Integer quotient: {0}", 7 / 3); Console.WriteLine("Negative integer quotient: {0}", -7 / 3); Console.WriteLine("Remainder: {0}", 7 % 3); // Force a floating point quotient. float dividend = 7; Console.WriteLine("Floating point quotient: {0}", dividend / 3); Console.WriteLine("\nDividing 8 by 5."); // Integer quotient is 1, remainder is 3. Console.WriteLine("Integer quotient: {0}", 8 / 5); Console.WriteLine("Negative integer quotient: {0}", 8 / -5); Console.WriteLine("Remainder: {0}", 8 % 5); // Force a floating point quotient. Console.WriteLine("Floating point quotient: {0}", 8 / 5.0); } } // Output: //Dividing 7 by 3. //Integer quotient: 2 //Negative integer quotient: -2 //Remainder: 1 //Floating point quotient: 2.33333333333333 //Dividing 8 by 5. //Integer quotient: 1 //Negative integer quotient: -1 //Remainder: 3 //Floating point quotient: 1.6
