WebBYCOL function. Applies a LAMBDA to each column and returns an array of the results. BYROW function. Applies a LAMBDA to each row and returns an array of the results. FALSE function. Returns the logical value FALSE. IF function. Specifies a logical test to perform. IFERROR function. WebThese axioms, which define a Boolean algebra, are often referred to as Huntington’s postulates [1]. We often use formulae to describe functions, but we have to keep in mind that the two are distinct. Many (in fact, an infinite number of) Boolean formulae can describe a Boolean function. The formula is equivalent to

WebDec 16, 2024 · XLOOKUP function In the worksheet shown, the formula in cell G5 is: The lookup_value is provided as 1, for reasons that become clear below. For the lookup_array, we use an expression based on Boolean logic: In the world of Boolean algebra, AND logic corresponds to multiplication (*), and OR logic corresponds to addition (+). WebDec 10, 2014 · Example 1. Using the "Equal to" operator with dates. You might be surprised to know that the Equal to logical operator cannot compare dates as easily as numbers. For example, if the cells A1 and A2 contain the date "12/1/2014", the formula =A1=A2 will return TRUE exactly as it should.. However, if you try either =A1=12/1/2014 or … WebThe OR function returns TRUE if any of its arguments evaluate to TRUE, and returns FALSE if all of its arguments evaluate to FALSE.. One common use for the OR function is to expand the usefulness of other functions that perform logical tests.
