If

Imagined conditions There are different types of conditions. Some are possible or likely, others are unlikely, and others are impossible: If the weather improves, we’ll go for a walk. (It is possible or likely that the weather will improve.) If the weather improved, we could go for a walk. (It is not likely that the weather will improve.) If the weather had improved, we could have gone for a walk. (The weather did not improve – fine weather is therefore an impossible condition.) These types of conditions are used in three types of sentences, called first, second and third conditional sentences. Imagined conditions: the second conditional We use the second conditional to talk about the possible result of an imagined situation in the present or future. We say what the conditions must be for the present or future situation to be different. If people complained, things would change. (People don’t complain at themoment.) conditional clause main clause if + past simple modal verb with future-in-the-past meaning ( should/ would/might/could) If you asked her nicely, she would say yes, I’m sure. We use a past form in the conditional clause to indicate a distance from reality, rather than indicating past time. We often use past forms in this way in English. first conditional second conditional If the flight ’s late, we ’ll miss our connection. (it’s possible or likely that the flight will be late) If there were more buses, we would leave the car at home. (it is unlikely that there w...

Rudyard Kipling, one of the most famous poets of the late British Empire, published "If—" in his 1910 book Rewards and Fairies. The poem's speaker advises his son to live with restraint, moderation, and composure. The son should always keep his wits about him, the speaker says, never overreacting; he should learn to be confident without being vain, accept hardships without dwelling on them, and behave with dignity. Living this way, the speaker suggests, will make the son a true man. This is a poem of advice not just from a father to a son, but from Fathers to Sons: a poem about an idealized kind of self-sufficient male virtue. Its worldview borrows heavily from • 1If you can keep your head when all about you 2 Are losing theirs and blaming it on you; 3If you can trust yourself when all men doubt you, 4 But make allowance for their doubting too: 5If you can wait and not be tired by waiting, 6 Or being lied about, don’t deal in lies, 7Or being hated don’t give way to hating, 8 And yet don’t look too good, nor talk too wise; 9If you can dream—and not make dreams your master; 10 If you can think—and not make thoughts your aim, 11If you can meet with Triumph and Disaster 12 And treat those two impostors just the same: 13If you can bear to hear the truth you’ve spoken 14 Twisted by knaves to make a trap for fools, 15Or watch the things you gave your life to, broken, 16 And stoop and build ’em up with worn-out tools; 17If you can make one heap of all your winnings 18 And risk it ...

In this article Determines whether any condition in a set is true ( If) or the result of a formula matches any value in a set ( Switch) and then returns a result or executes an action. Description The If function tests one or more conditions until a true result is found. If such a result is found, a corresponding value is returned. If no such result is found, a default value is returned. In either case, the returned value might be a string to show, a formula to evaluate, or another form of result. The Switch function evaluates a formula and determines whether the result matches any value in a sequence that you specify. If a match is found, a corresponding value is returned. If no match is found, a default value is returned. In either case, the returned value might be a string to show, a formula to evaluate, or another form of result. If and Switch are very similar, but you should use the best function for your situation: • Use If to evaluate a single condition. The most common syntax for this function is If( Condition, ThenResult, DefaultResult ), which provides the common “if … then … else …” pattern seen in other programming tools. • Use If to evaluate multiple unrelated conditions. In Power Apps (unlike Microsoft Excel), you can specify multiple conditions without having to nest If formulas. • Use Switch to evaluate a single condition against multiple possible matches. You can also use If in this case, but you'd need to repeat the formula for each possible match. You ca...

In this article Uses short-circuit evaluation to conditionally return one of two values. The If operator can be called with three arguments or with two arguments. Syntax If( [argument1,] argument2, argument3 ) If operator called with three arguments When If is called by using three arguments, the first argument must evaluate to a value that can be cast as a Boolean. That Boolean value will determine which of the other two arguments is evaluated and returned. The following list applies only when the If operator is called by using three arguments. Parts Term Definition argument1 Required. Boolean. Determines which of the other arguments to evaluate and return. argument2 Required. Object. Evaluated and returned if argument1 evaluates to True. argument3 Required. Object. Evaluated and returned if argument1 evaluates to False or if argument1 is a Boolean variable that evaluates to An If operator that is called with three arguments works like an IIf function except that it uses short-circuit evaluation. An IIf function always evaluates all three of its arguments, whereas an If operator that has three arguments evaluates only two of them. The first If argument is evaluated and the result is cast as a Boolean value, True or False. If the value is True, argument2 is evaluated and its value is returned, but argument3 is not evaluated. If the value of the Boolean expression is False, argument3 is evaluated and its value is returned, but argument2 is not evaluated. The following examp...

The Excel IF function runs a logical test and returns one value for a TRUE result, and another for a FALSE result. For example, to "pass" scores above 70: =IF(A1>70,"Pass","Fail"). More than one condition can be tested by nesting IF functions. The IF function can be combined with logical functions like AND and OR to extend the logical test. The IF function runs a logical test and returns one value for a TRUE result, and another value for a FALSE result.The result from IF can be a value, acell reference, or even another formula. By combining the IF function with other logical functions like Syntax The generic syntax for the IF function looks like this: =IF(logical_test,[value_if_true],[value_if_false]) The first argument, logical_test, istypically an expression that returns either TRUE or FALSE. The second argument, value_if_true, is the value to return when logical_test is TRUE. The last argument, value_if_false, is the value to returnwhen logical_test is FALSE. Both value_if_trueand value_if_false are optional, but you must provide one or the other. For example, if cell A1 contains 80, then: =IF(A1>75,TRUE) // returns TRUE =IF(A1>75,"OK") // returns "OK" =IF(A1>85,"OK") // returns FALSE =IF(A1>75,10,0) // returns 10 =IF(A1>85,10,0) // returns 0 =IF(A1>75,"Yes","No") // returns "Yes" =IF(A1>85,"Yes","No") // returns "No" Notice that text values like "OK", "Yes", "No", etc. must be enclosed in double quotes (""). However, numeric values should not be enclosed in quotes. Log...

If: conditions We often use if to introduce possible or impossible situations or conditions and their results. The situations or conditions can be real, imagined or uncertain: I usually make a sandwich to take to work if I have enough time. (real) If you don’t book now, you won’t get good tickets. (real) They’d have got the job done quicker if they’d had more people working on it. (imagined) Will you bring my glasses down if you go upstairs? (uncertain) If possible, if necessary We can sometimes leave words out after if to form fixed expressions: Check the temperature of your meat with a meat thermometer if possible. (if it’s possible or if that’s possible) Interest rates would have to rise if necessary to protect the pound, Mr John Smith, Shadow Chancellor, indicated yesterday on BBC TV’s Money Programme. If so, if not We use so or not after if when it is obvious what we are referring to: [from a job advertisement] Are you looking for part-time work? Do you want to work from home? If so, read on. (if you are looking for part-time work or if you want to work from home) You should all have received your booklist for the course by now. If not, please email the office. (if you haven’t received your booklist for the course by now) I’ll see you soon, definitely at the wedding, if not before. (if I don’t see you before the wedding) See also: • • If or when? • If or whether? • • Even if We use only if to express a strong condition, often an order or command, to mean ‘on the condi...
