Answer
Misusing constructors can lead to precision issues.
Using BigDecimal's double constructor can introduce precision errors. It's better to use the string constructor for precise values. For instance, creating BigDecimal from a double like 0.1 can lead to unexpected results, while `new BigDecimal("0.1")` maintains precision.
