Integer Calculator

Perform integer arithmetic with explicit validation and a clearly defined quotient rule for division.

Main Calculator

Division uses truncation toward zero, so -5 / 2 = -2.
Result
5
10 + -5 = 5

Validation

Both inputs must be safe integers. Blank text, decimals, and values outside the safe integer range are rejected.

Worked Example

14 / -4 truncates toward zero and becomes -3.

Formula

+, -, and * follow ordinary integer arithmetic.
/ returns Math.trunc(left / right).

Frequently Asked Questions

Why use truncation for division?

It gives a predictable integer quotient and matches the calculator's stated rule.

Can I divide by zero?

No. Division by zero is rejected before the calculation runs.
