![]() To obtain the quotient of the two operands as a floating-point number, use the float, double, or decimal type: Console.WriteLine(13 / 5.0) // output: 2.6Ĭonsole.WriteLine((double)a / b) // output: 2.6įor the float, double, and decimal types, the result of the / operator is the quotient of the two operands: Console.WriteLine(16.8f / 4.1f) // output: 4.097561Ĭonsole.WriteLine(16.8d / 4.1d) // output: 4.09756097560976Ĭonsole.WriteLine(16.8m / 4.1m) // output: 4.0975609756097560975609756098 Integer divisionįor the operands of integer types, the result of the / operator is of an integer type and equals the quotient of the two operands rounded towards zero: Console.WriteLine(13 / 5) // output: 2Ĭonsole.WriteLine(-13 / 5) // output: -2Ĭonsole.WriteLine(13 / -5) // output: -2Ĭonsole.WriteLine(-13 / -5) // output: 2 The division operator / divides its left-hand operand by its right-hand operand. The unary * operator is the pointer indirection operator. The multiplication operator * computes the product of its operands: Console.WriteLine(5 * 2) // output: 10Ĭonsole.WriteLine(0.5 * 2.5) // output: 1.25Ĭonsole.WriteLine(0.1m * 23.4m) // output: 2.34 The ulong type doesn't support the unary - operator. Console.WriteLine(+4) // output: 4Ĭonsole.WriteLine(b.GetType()) // output: System.Int64Ĭonsole.WriteLine(-double.NaN) // output: NaN The unary - operator computes the numeric negation of its operand. The unary + operator returns the value of its operand. The result of -x is the value of x after the operation, as the following example shows: double a = 1.5 The result of x- is the value of x before the operation, as the following example shows: int i = 3 The decrement operator is supported in two forms: the postfix decrement operator, x-, and the prefix decrement operator, -x. The operand must be a variable, a property access, or an indexer access. The unary decrement operator - decrements its operand by 1. The result of ++x is the value of x after the operation, as the following example shows: double a = 1.5 ![]() The result of x++ is the value of x before the operation, as the following example shows: int i = 3 The increment operator is supported in two forms: the postfix increment operator, x++, and the prefix increment operator, ++x. ![]() The unary increment operator ++ increments its operand by 1. The result type of a compound assignment expression is the type of the left-hand operand. ![]() The ++ and - operators are defined for all integral and floating-point numeric types and the char type. For more information, see the Numeric promotions section of the C# language specification. When operands are of different integral or floating-point types, their values are converted to the closest containing type, if such a type exists. When operands are of other integral types ( sbyte, byte, short, ushort, or char), their values are converted to the int type, which is also the result type of an operation. In the case of integral types, those operators (except the ++ and - operators) are defined for the int, uint, long, and ulong types. Those operators are supported by all integral and floating-point numeric types. Binary * (multiplication), / (division), % (remainder), + (addition), and - (subtraction) operators.Unary ++ (increment), - (decrement), + (plus), and - (minus) operators.The following operators perform arithmetic operations with operands of numeric types: ![]()
