Which two operators are used as calculation context operators?

The 'In' operator is a calculation context operator used to explicitly define the set of dimensions within which a measure is calculated, overriding the default block context.

The 'Where' operator is a calculation context operator used to apply a filter condition within a formula, restricting the rows included in the calculation without changing the report structure.

'Selec' is not a valid Web Intelligence formula operator; it appears to be a misspelling and has no role in calculation context syntax.

'Having' is an aggregate filter keyword used in SQL and in Web Intelligence query filters, but it is not a calculation context operator used within formulas.
