             Summary: Sql. TypeSystem. Default implementation of 
getDefaultPrecision FLOAT and DECIMAL returns the same value.
                 Key: IGNITE-18556
                 URL: https://issues.apache.org/jira/browse/IGNITE-18556
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Maksim Zhuravkov


Default implementation of TypeSystem::getDefaultPrecision, provided by Calcite, 
returns the same value for FLOAT and DOUBLE types. Such behaviour causes 
TypeFactory::leastRestrictiveType to return different results for (FLOAT, 
DOUBLE) and (DOUBLE, FLOAT).

We fixed getDefaultPrecision to return different values to the problem 
leastRestrictiveType in IGNITE-18163.

1) Investigate how these change affect behaviour of other operators

2) Choose appropriate value for default precision.
