------------------------------------

             Summary: TypeCoercion for arithmetic operations is never invoked
                 Key: CALCITE-7148
                 URL: https://issues.apache.org/jira/browse/CALCITE-7148
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.40.0
            Reporter: Mihai Budiu


I don't really know how TypeCoercion is supposed to be used, but the method 
binaryAritmeticCoercion is essentially never invoked by Calcite.

I suspect that this is the cause of many complications, since many functions in 
the runtime have to consider all possible argument types in their 
implementations.
