             Summary: Sql. Align rule of conversion between numerics
                 Key: IGNITE-22817
                 URL: https://issues.apache.org/jira/browse/IGNITE-22817
             Project: Ignite
          Issue Type: Bug
          Components: sql
            Reporter: Konstantin Orlov
            Assignee: Konstantin Orlov


Class {{IgniteMath}} contains set of methods to do conversion from one numeric to another with bound check. The problem is that rules of bound check differs from one type pair to another: some pairs has strict rules, some pairs allow to have decimal part of arbitrary size, some pairs do bound check after rounding initial value with HALF UP strategy.

We need to make bound check consistent for all type pairs. Since we are going to truncate decimal part during conversion to. integers, it's suggested to do bound check accordingly.
