Answer
Use setScale for consistent decimal places.
When working with currencies, consistent scale (i.e., number of decimal places) is crucial for readability and accuracy. `setScale` can enforce this. For instance, `new BigDecimal("19.99").setScale(2, RoundingMode.HALF_UP)` ensures two decimal places, aligning with most currency formats.
