This chapter describes the functions and the IF statements. When a function appears in an expression in FORTRAN, the argument of the function is evaluated first. Then, the function itself is evaluated. If there is more than one function in an expression, the functions are evaluated from left ...
The IF function allows you to make a logical comparison between a value and what you expect by testing for a condition and returning a result if True or False. =IF(Something is True, then do something, otherwise do something else) So an IF statement can have two results. Th...
The IF function is one of the most popular functions in Excel, and it allows you to make logical comparisons between a value and what you expect. So an IF statement can have two results. The first result is if your comparison is True, the second if your comparison is False. ...
Let's write a function that does the same thing as anifstatement. def if_function(condition, true_result, false_result): """ Return true_result if condition is a true value, and false_result otherwise. >>> if_function(True, 2, 3) 2 >>> if_function(False, 2, 3) 3 >>> if_fu...

This article explores the useful function SQL IF statement inSQL Server. 本文探讨了SQL Server中有用的函数SQL IF语句。 介绍(Introduction) In real life, we make decisions based on the conditions. For example, look at the following conditions. ...
This function returns BOOLEAN results and categorizes them into 3 categories: TRUE, FALSE, and UNKNOWN. Similar to the IF Statement Tableau, IIF Statement returns a TRUE value when the conditional expression is satisfied, and a FALSE value for a failed condition. However, when the data contains...
The Excel IF Statement function tests a given condition and returns one value for a TRUE result, and another for a FALSE result.
There is also an IF() function, which differs from the IF statement described here. See Section 14.5, “Flow Control Functions”. The IF statement can have THEN, ELSE, and ELSEIF clauses, and it is terminated with END IF. If a given search_condition evaluates to true, the corresponding...
IF Function in Excel vs. IF Statement in VBA IF Statements are designed to execute the same functions, but they differ in several ways in how they work. The Excel IF statement works by checking if the condition is met and returns a value (TRUE). Otherwise, it returns the value FALSE. ...
