Integer Calculator

An integer is any whole number, positive or negative, including zero. Examples include -100, -1, 0, 1, and 100. Unlike floating-point numbers, integers have no decimal or fractional component.

Yes. You can enter negative values in either or both number fields. The calculator correctly applies the selected operation — addition, subtraction, multiplication, or division — to positive and negative integers alike.

The result is truncated (not rounded) to the nearest whole number toward zero. For example, 7 ÷ 2 returns 3, and −7 ÷ 2 returns −3. Division by zero is not allowed and will be flagged as an error.

These are alternative number bases used in computing. Binary (base-2) uses only 0 and 1, octal (base-8) uses digits 0–7, and hexadecimal (base-16) uses digits 0–9 and letters A–F. The calculator converts the integer result into each of these bases automatically.

Adding a negative number is the same as subtracting its positive equivalent (e.g. 5 + (−3) = 2). Subtracting a negative number is the same as adding its positive equivalent (e.g. 5 − (−3) = 8). The calculator applies these sign rules automatically.

This calculator is designed for integers (whole numbers). If you enter a decimal, it will be truncated to a whole number before the operation is performed, consistent with integer arithmetic rules.

The calculator supports four operations: addition (+), subtraction (−), multiplication (×), and division (÷). Select the desired operation from the dropdown menu between the two number fields.

Regular division can produce a decimal result (e.g. 10 ÷ 3 = 3.333…). Integer division discards the decimal portion, returning only the whole number quotient (e.g. 10 ÷ 3 = 3). This mirrors how integer division works in most programming languages.
