Understanding BigDecimal in JavaScript

Handling precise decimal arithmetic operations is a common requirement in many software applications, especially those involving financial calculations. Traditionally, languages like Java provide a robust solution in the form of the BigDecimal class. However, when it comes to JavaScript, developers might wonder whether there's a BigDecimal equivalent or how to handle precise decimal operations. In this guide, we'll dive into this topic and explore various solutions.

Is there a BigDecimal in JavaScript?

JavaScript, being a high-level, interpreted programming language, is widely utilized for web development. Despite its versatility, JavaScript’s built-in handling of numbers can be a limitation for precision arithmetic operations, especially involving floating-point numbers due to rounding errors.

The simple answer to the question is no; JavaScript does not have a native BigDecimal class like Java does. However, this doesn't mean that precise decimal arithmetic is off the table in JavaScript. There are multiple libraries available that extend JavaScript's capabilities to handle such operations accurately.
