Liang-Chi Hsieh created SPARK-8677: -------------------------------------- Summary: Decimal divide operation throws ArithmeticException Key: SPARK-8677 URL: https://issues.apache.org/jira/browse/SPARK-8677 Project: Spark Issue Type: Bug Components: SQL Reporter: Liang-Chi Hsieh
Please refer to [BigDecimal doc|http://docs.oracle.com/javase/1.5.0/docs/api/java/math/BigDecimal.html] {quote} ... the rounding mode setting of a MathContext object with a precision setting of 0 is not used and thus irrelevant. In the case of divide, the exact quotient could have an infinitely long decimal expansion; for example, 1 divided by 3. {quote} Because we provide a MathContext.UNLIMITED in toBigDecimal, Decimal divide operation will throw the following exception: {code} val decimal = Decimal(1.0, 10, 3) / Decimal(3.0, 10, 3) [info] java.lang.ArithmeticException: Non-terminating decimal expansion; no exact representable decimal result.
