Modular Remainder

Definition

Modular remainder refers to the result obtained when one number is divided by another, specifically within modular arithmetic. This mathematical concept is fundamental in cryptography and computer science, forming the basis for many hashing algorithms, public-key encryption schemes, and error-correction codes. It ensures that calculations remain within a fixed range, which is essential for operations on finite sets of numbers. The modular remainder is critical for maintaining computational integrity and security in digital systems.
