TreatAsType is useful if you are using values in a calculation that are not necessarily in the native type for the formula. For example, if a TextBox control's Text property is being used to enter a numeric value, the _CALCMANAGER_ by default converts the contents of the TextBox to a Double using the Invariant Culture. This may not always be the desired effect. Setting TreatAsType to double in this example would convert the Text of the TextBox to a Double using the Invariant Culture before passing the value on to the _CALCMANAGER_.
