>                 URL: https://issues.apache.org/jira/browse/IMPALA-6202
>             Project: IMPALA
>          Issue Type: Bug
>    Affects Versions: Impala 2.11.0
>            Reporter: Jim Apple
>            Assignee: Yongjun Zhang
>            Priority: Major

> The docs say:
> "mod(numeric_type a, same_type b) Purpose: Returns the modulus of a number. Equivalent to the % arithmetic operator."
> and
> "fmod(double a, double b), fmod(float a, float b) Purpose: Returns the modulus of a floating-point number. Equivalent to the % arithmetic operator."
> But these can't both be true:
> {noformat}
> [localhost:21000] > select typeof(9.9 % 3), typeof(mod(9.9, 3)), typeof(fmod(9.9, 3));
> +-----------------+---------------------+----------------------+
> | typeof(9.9 % 3) | typeof(mod(9.9, 3)) | typeof(fmod(9.9, 3)) |
> +-----------------+---------------------+----------------------+
> | DECIMAL(2,1)    | DECIMAL(4,1)        | FLOAT                |
> +-----------------+---------------------+----------------------+
> {noformat}
