> DataFrameStatFunctions.approxQuantile derives approx_percentile accuracy from relativeError. Double.PositiveInfinity passes the existing non-negative relative-error validation, but ceil(1.0 / relativeError) produces accuracy 0, which approx_percentile rejects. Clamp the derived accuracy to at least 1. See PR: https://github.com/apache/spark/pull/58173
