IIf Function
평가된 식의 논리값에 따라 두 가지의 가능한 함수 결과 중 하나를 구합니다.
IIf (Bool As Boolean, Variant1 As Variant, Variant2 As Variant) As VariantBool: 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 Returns the maximum of 3 values
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 Bad usage of function IIf
Function Inverse(A As Double) As Double
Inverse = IIf( A = 0, 0, 1/A )
End Function
