This third version (V3) explores the potential applications of the arithmetic function F(n) = n mod dr(n), previously formalized and analyzed in its structural properties. While not intended to replace established tools in specific domains, the function exhibits computational simplicity and structural characteristics that make it suitable as a component in various applied contexts. In particular, possible uses are identified in value space reduction, preliminary consistency checks, data partitioning, embedded systems, machine learning preprocessing, and real-time data processing. The analysis focuses on realistic and technically consistent scenarios, ensuring that all proposed applications remain compatible with the mathematical properties established in previous versions.
