[C++] Comparison kernel(s) for decimals

    XMLWordPrintableJSON

Details

    Description

      Even decimal-decimal comparisons return an error:

      > Scalar$create(1.5)$cast(decimal(15, 2)) > Scalar$create(1.1)$cast(decimal(15, 2))
      Error: NotImplemented: Function greater has no kernel matching input types (scalar[decimal128(15, 2)], scalar[decimal128(15, 2)])
      

      Ideally, we would also be able to (autocast in order to) compare decimal-float or decimal-integer.
