Answer
'BigDecimal' offers better precision for financial calculations.
While 'double' is suitable for general calculations, it may cause precision issues with currency due to binary representation. 'BigDecimal' is preferred in e-commerce for prices because it avoids rounding errors and provides exact precision. For instance, to store a price of $19.99, use 'BigDecimal price = new BigDecimal("19.99");' to ensure accurate calculations.
