------------------------------------
Assignee: Mihai Budiu
> The meaning of negation for unsigned numbers is not defined
> -----------------------------------------------------------
>
> Key: CALCITE-7360
> URL: https://issues.apache.org/jira/browse/CALCITE-7360
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.41.0
> Reporter: Mihai Budiu
> Assignee: Mihai Budiu
> Priority: Minor
> Labels: pull-request-available
>
> Some time ago unsigned integer types were introduced in Calcite.
> They allow all arithmetic operations as signed types.
> However, the meaning of negation is not defined. Using negation in a quidem
> test causes an exception, since the implementation is incorrect.
> Questions:
> * Should negation be allowed at all?
> * Should it coerce the value to a larger integer type?
> * Or should it work as in C?
