[SPARK-8800][SQL] Fix inaccurate precision/scale of Decimal division
operation
JIRA: https://issues.apache.org/jira/browse/SPARK-8800
Previously, we turn to Java BigDecimal's divide with specified
ROUNDING_MODE to avoid non-terminating decimal expansion problem. However, as
@JihongMA reported, for the division operation on some specific values, we get
inaccurate results.
