Description:

This built-in compiler plug-in of ALib Expressions , performs auto-casts only if two different types are given. In this case, the following casts are performed:

If one argument is of type Types::String , the other is converted to string. The expression function returned for (optional) decompilation is "String()".
If one argument is of type Types::Float and the other of type Types::Integer , the integral value is casted to floating point. The expression function returned for (optional) decompilation is "Float()".
If one argument is of type Types::Float and the other of type Types::Boolean , the boolean value is casted to floating point. The expression function returned for (optional) decompilation is "Float()".
If one argument is of type Types::Integer and the other of type Types::Boolean , the boolean value is casted to integer. The expression function returned for (optional) decompilation is "Integer()".
If one argument is of type Types::Boolean , the other is converted to boolean using an internal callback function that simply invokes box-function FIsTrue . The expression function returned for (optional) decompilation is "Boolean()".
