GrapeCity.CalcEngine.Functions Namespace / CalcIfFunction Class / Evaluate Method / Evaluate(Object[]) Method

The args contains three items: logical_test, value_if_true and value_if_false.

logical_test is any value or expression that can be evaluated to true or false. For example, A10=100 is a logical expression; if the value in cell A10 is equal to 100, the expression evaluates to true. Otherwise, the expression evaluates to false. This argument can use any comparison calculation operator.

value_if_true is the value that is returned if logical_test is true. For example, if this argument is the text string "Within budget" and the logical_test argument evaluates to true, then the IF function displays the text "Within budget". If logical_test is true and value_if_true is blank, this argument returns 0 (zero). To display the word true, use the logical value true for this argument. Value_if_true can be another formula.

value_if_false is the value that is returned if logical_test is false. For example, if this argument is the text string "Over budget" and the logical_test argument evaluates to false, then the IF function displays the text "Over budget". If logical_test is false and value_if_false is omitted, (that is, after value_if_true, there is no comma), then the logical value false is returned. If logical_test is false and value_if_false is blank (that is, after value_if_true, there is a comma followed by the closing parenthesis), then the value 0 (zero) is returned. Value_if_false can be another formula.

    args

    The args contains three items: logical_test, value_if_true and value_if_false.

    logical_test is any value or expression that can be evaluated to true or false. For example, A10=100 is a logical expression; if the value in cell A10 is equal to 100, the expression evaluates to true. Otherwise, the expression evaluates to false.

    value_if_true is the value that is returned if logical_test is true.

If logical_test is false and value_if_false is omitted, (that is, after value_if_true, there is no comma), then the logical value false is returned. If logical_test is false and value_if_false is blank (that is, after value_if_true, there is a comma followed by the closing parenthesis), then the value 0 (zero) is returned. Value_if_false can be another formula.

    Return Value
