a mod b = r
where
a = b ร q + r
and 0 โค r < |b|
(a: dividend, b: divisor, q: quotient, r: remainder)
What Is the Modulus Calculator?
The Modulus Calculator is a simple yet powerful tool that helps you determine the remainder when one number is divided by another. Whether you're a student, teacher, or professional, this tool provides a quick way to understand and calculate the result of a modulus operation.
How It Works
The modulus operation finds the remainder after dividing one number (the dividend) by another (the divisor). For example, if you divide 17 by 5, the result is 3 with a remainder of 2 โ so 17 mod 5 = 2
.
