BigDecimalMethodWithoutRoundingCalled

Reports calls to divide() or setScale() without a rounding mode argument.

Such calls can lead to an ArithmeticException when the exact value cannot be represented in the result (for example, because it has a non-terminating decimal expansion).

Specifying a rounding mode prevents the ArithmeticException.

Example:

BigDecimal.valueOf(1).divide(BigDecimal.valueOf(3));
