Function GetLogical( _
   ByVal index As Integer _
) As Boolean

bool GetLogical( 
   int index
)

Parameters

index

Non-logical arguments are converted to a logical value if possible. Otherwise, false is returned by this method, and an internal flag is set indicating that an error has occurred, causing the result of the formula to be an error.

Note that this method has the side effect of converting a range or array to a single value. Use GetArrayDimensions and GetArrayValue to get the dimensions and values of a range or array.
