Number

The Number module provides a set of utility functions for working with numbers in JavaScript/TypeScript. These functions allow you to perform common operations such as checking number types, testing mathematical properties, and executing numerical calculations.

All functions are designed to be simple, efficient, and easy to use, following best development practices.
