1. What is Modulus Operation?

The modulus operation finds the remainder after division of one number by another. In mathematics, it's often called the "remainder operation."

2. How Does Modulus Work?

The modulus operation is calculated as:

\[ a \mod b = remainder \ of \ a \div b \]

Where:

Example: \( 10 \mod 3 = 1 \) because 10 divided by 3 is 3 with a remainder of 1.

3. Practical Applications

Details: Modulus operations are used in programming, cryptography, time calculations, and determining even/odd numbers.

4. Using the Calculator

Tips: Enter any number for dividend (a) and any non-zero number for divisor (b). The calculator will return the remainder of a divided by b.

5. Frequently Asked Questions (FAQ)

Q1: What happens if b is zero?
A: Division by zero is undefined, so the calculator requires b to be non-zero.

Q2: Can modulus be negative?
A: Yes, the result takes the sign of the dividend (a). For example, -10 mod 3 = -1.

Q3: How is modulus different from remainder?
A: In mathematics, they're the same. Some programming languages handle negative numbers differently.

Q4: What's the difference between mod and division?
A: Division gives the quotient, while modulus gives the remainder.

Q5: Can modulus be used with decimals?
A: Yes, the calculator supports decimal numbers. Example: 10.5 mod 3.2 = 0.9.
