How to represent large numbers in your Node.js app

JavaScript faces challenges in accurately representing numbers with several significant digits due to its use of the 64-bit double-precision binary floating-point format, which can lead to loss of precision for integers outside the safe integer range. To address this, JavaScript offers the BigInt type for managing large integers, allowing basic mathematical operations but not integration with the built-in Math object. For more comprehensive handling of large numbers, third-party packages like Math.js, bignumber.js, and JS Big Decimal provide additional functionality. These libraries, while differing in features and bundle sizes, enable more precise arithmetic operations beyond the limitations of JavaScript's native number handling. Math.js is a feature-rich general math library, whereas bignumber.js and JS Big Decimal focus specifically on managing large numbers, with the latter offering the smallest bundle size but limited operations. These tools are essential for developers needing to work with large numerical values without encountering precision issues inherent to JavaScript's native capabilities.
