What Is This Tool?
This Online Modulo Calculator computes the remainder when one integer is divided by another, a key operation in arithmetic and computer science known as the modulo operation.
How to Use This Tool?
- Enter the dividend integer (A), the number you want to divide
- Enter the divisor integer (B), the number you divide by
- Click the calculate button to compute the remainder
- View the result, which is the remainder \(R = A - B \times \lfloor A/B \rfloor\)
Key Features
- Calculates the remainder of integer division (A mod B) accurately
- Uses exact integer arithmetic to avoid floating-point errors
- Supports common modulo use cases in programming and mathematics
- Fast, easy to use, and accessible through your browser
Examples
- Calculate 29 mod 5: Divide 29 by 5 to get quotient 5 and remainder 4
- Using the formula: \(R = 29 - (5 \times 5) = 4\), so the remainder is 4
Common Use Cases
- Finding remainders in arithmetic calculations
- Programming tasks involving loops and conditional operations
- Clock mathematics and cyclical pattern calculations
- Applications in hashing, cryptography, and number theory
Tips & Best Practices
- Ensure input values are integers for accurate results
- Be aware that handling of negative numbers may vary by system
- Use integer division cautiously when interpreting the quotient
- Double-check divisor input to avoid division by zero errors
Limitations
- Only supports integer values for dividend and divisor
- Negative number remainders may differ depending on implementation
- Not designed for floating-point or decimal values
Frequently Asked Questions
- What does the modulo operation compute?
- It calculates the remainder after dividing one integer by another.
- Can I use this tool with decimal numbers?
- No, the calculator only accepts integer input values for accurate results.
- Why is the modulo operation useful?
- It is widely used in programming, cryptography, cyclic calculations, and mathematical problem solving.
Key Terminology
- Dividend (A)
- The integer number being divided in the modulo operation.
- Divisor (B)
- The integer number by which the dividend is divided.
- Remainder (R)
- The result of the modulo operation representing what remains after division.
