What does BigDecimal mean in Java?

BigDecimal is a class in Java that is used for performing high-precision decimal calculations. It can handle a larger range of numbers compared to regular primitive data types like double or float, and can maintain higher precision.

BigDecimal values can represent decimal numbers of any length without losing precision. It supports basic mathematical operations such as addition, subtraction, multiplication, and division, and rounding can be performed to control precision and rounding methods.

BigDecimal is suitable for scenarios that require precise calculations, such as financial applications, currency calculations, scientific computations, etc. It offers a reliable way to handle decimal values and avoids precision issues with floating-point calculations.
