You will have to use provide a MathContext or a RoundingMode telling how you want to handle this. For example:. Web. Web. For example, division by zero throws an ArithmeticException, and division of a negative by a positive yields a negative (or zero) remainder. All of the details in the Spec concerning overflow are ignored, as BigIntegers are made as large as necessary to accommodate the results of an operation.. In the case of the divide, the exact quotient could have an infinitely long decimal expansion; for example, 1 divided by 3. If the quotient has a non terminating decimal expansion and the operation is specified to return an exact result, an ArithmeticException is thrown. Web. Web.

Moreover, equals will compare two BigDecimal on value and scale, which means that even this would fail: BigDecimal bd1=new BigDecimal("0"); BigDecimal bd2=new BigDecimal("0.0"); bd1.equals(bd2) // will return false. You should use compareTo() in order to compare the value only. The BigDecimal javadoc says this: The BigDecimal class gives its user complete control over rounding behavior. If no rounding mode is specified and the exact result cannot be represented, an exception is thrown; otherwise, calculations can be carried out to a chosen precision and rounding mode by supplying an appropriate MathContext object to.
