> The decimal fuzz test has been helpful in finding bugs in the decimal data type. However, currently it only supports arithmetic operations. Here are some ideas about how it can be expanded:
>  * Add binary predicates (greater than, less than, etc)
>  * Add operations with other data types for example, (decimal + bigint), (bigint <= int).
>  * More complex expressions (d1 + d2 / d3 % d4)
>  * Add other decimal functions, such as round(), ceil()
