Which says IF(the value in cell F2 equals 1, then return the value in cell D2, IF the value in cell F2 equals 2, then return the value in cell D3, and so on, finally ending with the value in cell D8 if none of the other conditions are met). Remarks Which says IF(A2 is Greater Than 89, then return a "A", IF A2 is Greater Than 79, then return a "B", and so on and for all other values less than 59, return an "F"). Example 2 This is one of the reasons why many developers and many style guides (e.g. standardjs) prefer === and almost never use ==.

Result to be returned if logical_testN evaluates to TRUE. Each value_if_trueN corresponds with a condition logical_testN. Can be empty. IFS(logical_test1, value_if_true1, [logical_test2, value_if_true2], [logical_test3, value_if_true3],…)

Example

If a logical_test argument is supplied without a corresponding value_if_true, this function shows a "You've entered too few arguments for this function" error message. It's worth talking about falsy values' loose comparisons with ==, which uses ToNumber() and can cause some confusion due to the underlying differences. They effectively form three groups: Peter Grant is facing fatherhood, and an uncertain future, with equal amounts of panic and enthusiasm. Rather than sit around, he takes a job with emigre Silicon Valley tech genius Terrence Skinner's brand new London start up - the Serious Cybernetics Company. Drawn into the orbit of Old Street's famous 'silicon roundabout', Peter must learn how to blend in with people who are both civilians and geekier than he is. Compared to his last job, Peter thinks it should be a doddle. But magic is not finished with Mama Grant's favourite son.

new Number(0) and new Boolean(false) - they're objects, which are truthy, but == sees their values, which == false. You might think if (value && value == false) alert('Huh?') is a logical impossibility that couldn't happen, but it will, for: and '0' - they're non-empty strings, which are truthy, but Javascript's == matches numbers with equivalent strings (e.g. 42 == "42"). Since 0 == false, if "0" == 0, "0" == false.

Some more truthy values

To specify a default result, enter TRUE for your final logical_test argument. If none of the other conditions are met, the corresponding value will be returned. In Example 1, rows 6 and 7 (with the 58 grade) demonstrate this.
