caidezhi removed a comment on issue #10333: [FLINK-14970]Doomed test for equality to NaN URL: https://github.com/apache/flink/pull/10333#issuecomment-562493939 Hi @KurtYoung , i also aware of that. Calcite uses BigDecimal for handling DOUBLE, FLOAT. when we pass unnormal numerical value((eg: INFINITY, NaN) literalType=DoubleType, literalValue=null are passed to method "GenerateUtils.generateLiteral", the program will go to another branch, the pattern matching which has bug will not cause any impact. can we just remove the pattern matching logic to make it clean? if it is ok, i will make another commit for this PR. Thanks.
