CHAPTER 8 EXPRESSIONS AND OPERATORS

Simple Arithmetic Operators

The simple arithmetic operators perform the four basic arithmetic operations and are listed in Table 8-6. These operators are binary and left-associative.

Table 8-6. The Simple Arithmetic Operators

The arithmetic operators perform the standard arithmetic operations on all the predefined simple arithmetic types.

The following are examples of the simple arithmetic operators:

CHAPTER 8 EXPRESSIONS AND OPERATORS

The Remainder Operator

The remainder operator (%) divides the first operand by the second operand, ignores the quotient, and returns the remainder. Table 8-7 gives its description.

The remainder operator is binary and left-associative.

Table 8-7. The Remainder Operator

The following lines show examples of the integer remainder operator:

•0 % 3 = 0, because 0 divided by 3 is 0 with a remainder of 0.

•1 % 3 = 1, because 1 divided by 3 is 0 with a remainder of 1.

•2 % 3 = 2, because 2 divided by 3 is 0 with a remainder of 2.

•3 % 3 = 0, because 3 divided by 3 is 1 with a remainder of 0.

•4 % 3 = 1, because 4 divided by 3 is 1 with a remainder of 1.

The remainder operator can also be used with real numbers to give real remainders.

Console.WriteLine("0.0f % 1.5f is {0}" , 0.0f % 1.5f);

Console.WriteLine("0.5f % 1.5f is {0}" , 0.5f % 1.5f);

Console.WriteLine("1.0f % 1.5f is {0}" , 1.0f % 1.5f);

Console.WriteLine("1.5f % 1.5f is {0}" , 1.5f % 1.5f);

Console.WriteLine("2.0f % 1.5f is {0}" , 2.0f % 1.5f);

Console.WriteLine("2.5f % 1.5f is {0}" , 2.5f % 1.5f);

This code produces the following output:
