This project provides a collection of base utilities for working with double-precision floating-point numbers in JavaScript, including functions for arithmetic operations, bit manipulation, type conversions, and validation. It's designed for developers who need precise control over 64-bit floating-point number operations, particularly in scientific computing, numerical analysis, or performance-critical applications where understanding the underlying representation of floating-point values is important.
