Restituisce uno dei due possibili risultati di una funzione, in base al valore logico dell'espressione valutata.
IIf (Bool As Boolean, Variant1 As Variant, Variant2 As Variant) As Variant
Bool: Any expression that you want to evaluate. If the expression evaluates to True, the function returns the value of Variant1, otherwise it returns the value of Variant2.
Variant1, Variant2: Any expression, one of which will be returned as the function result, depending on the logical evaluation.
IIf evaluates both Variant1 and Variant2 even if it returns only one of them. If one of the expressions results in error, the function returns the error. For example, do not use IIF to bypass a possible division by zero result.
REM restituisce al massimo 3 valori
Function Max (A As Double, B As Double, C, As Double) As Double
Max = IIf( A >= B, A, B)
Max = IIf( C >= Max, C, Max)
End Function
REM uso sbagliato della funzione IIf
Function Inverse(A As Double) As Double
Inverse = IIf( A = 0, 0, 1/A )
End Function
