Description

Expressions are currently evaluated without taking the target field type into account. This leads to strange behavior. Values are sometimes formatted for representation, but are not adjusted in memory.

I propose to add a method to define a target field on an expression. After evaluating an expression, the result should be converted to match these specifications of the target field (length, precision, type).
