About Modulus Calculator
The Modulus Calculator helps you quickly compute the remainder when one number is divided by another. Just enter the two numbers—the dividend and the divisor—and the tool instantly shows the result of the modulus operation (also known as modulo or %). It’s fast, simple, and useful for both everyday tasks and advanced math.
This tool is ideal for:
- Solving division problems with remainders
- Working with clock arithmetic or cyclic patterns
- Programming logic (e.g., even/odd checks, wrapping values)
- Cryptography and modular arithmetic applications
- Math problems involving factors, divisibility, or number theory
Notes:
- Enter any two numbers: the first as the dividend, the second as the divisor.
- Supports positive and negative integers and decimals.
- Shows the remainder after dividing the first number by the second.
- Division by zero is not allowed—if attempted, the result will remain blank or show an error.
- Useful for both basic arithmetic and programming-related tasks.
How to Use the Modulus Calculator
This tool calculates a % b (the remainder when a is divided by b).
- Enter two numbers: the dividend (a) and the divisor (b).
- It automatically computes the remainder (modulus).
- Click Reset to clear the inputs.
- Works with both integers and decimal numbers.
Frequently Asked Questions (FAQs)
1. What is the modulus?
The modulus is the remainder left when one number is divided by another.
2. Does this work with decimals?
Yes, this calculator supports both integers and decimal numbers.
3. Can the divisor be zero?
No. Division by zero is undefined. The calculator will show an error.
