ASF GitHub Bot updated SPARK-60651:
-----------------------------------
Labels: pull-request-available (was: )
> Allow decimal remainders with integral quotients wider than the math context
> ----------------------------------------------------------------------------
>
> Key: SPARK-60651
> URL: https://issues.apache.org/jira/browse/SPARK-60651
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 5.0.0
> Reporter: Linhong Liu
> Priority: Major
> Labels: pull-request-available
>
> Decimal remainder can throw ArithmeticException: Division impossible when the
> integral quotient exceeds the 39-digit MathContext, even though the remainder
> is representable. For example, the remainder of
> 99999999999999999999999999999999999999 divided by 0.0007 is 0.0004, and pmod
> of its negative by 0.0007 is 0.0003. Preserve the existing context-based
> operation for successful inputs and retry with exact remainder only if that
> operation throws. Keep zero-divisor handling unchanged. Regression coverage
> includes both signs, remainder and pmod, quotient precision boundaries, zero
> divisors, scale preservation, and extreme-scale cases that already succeed
> with the existing operation.
