Answer
BigDecimal provides precision essential for financial calculations.
In Java, BigDecimal is used for currency calculations to avoid precision errors inherent in the binary representation of floating-point numbers, such as double. For example, adding 0.1 and 0.2 using double can result in 0.30000000000000004, while BigDecimal handles this precisely.
