IF(logical_test, [value_if_true], [value_if_false])

• logical_test (Required)

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.

YACAR-YACARA CONSULTS: Financial Modelling (Intermediate)

IF(logical_test, [value_if_true], [value_if_false])

• value_if_true Optional. The value that you want to be returned if the logical_test argument evaluates to TRUE.

• For example, if the value of this argument is the text string “QUALIFIED" and the logical_test argument evaluates to TRUE, the IF function returns the text "Within budget."

• If logical_test evaluates to TRUE and the value_if_true argument is omitted (that is, there is only a comma following the logical_test argument), the IF function returns 0 (zero). To display the word TRUE, use the logical value TRUE for the value_if_true argument.
