# IIf Function

Повертає один з двох можливих результатів функції залежно від логічного значення виразу.

### Синтаксис:

    IIf (Bool As Boolean, Variant1 As Variant, Variant2 As Variant) As Variant

### Параметри:

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.
