Overview
A reliable BigDecimal implementation in Dart inspired by Java's BigDecimal, designed to handle precise decimal arithmetic without floating-point errors. It supports arbitrary-precision calculations, ensuring accuracy for financial and scientific applications. The package is rigorously tested to avoid common bugs found in other implementations, making it ideal for use cases requiring exact decimal representation and rounding control. It works across all major platforms including mobile, web, and desktop.
