Déréel

Déréel is a mathematical operation used to convert numbers from real numbers to a finite set of integers, typically in cryptography or data encoding. It "reduces" any real number to a specific range, often by removing its fractional part modulo a given number, ensuring the result stays within a specified boundary. Essentially, it maps continuous (real) values into a discrete, finite set, helping to process or secure information efficiently. This operation maintains the essential structure needed for mathematical or computational tasks involving modular arithmetic, making complex real values manageable within finite systems.
