If and or excel exercises

В формуле, использованной в примере выше, вычисление суммы комиссионных выполняется в самой функции ЕСЛИ . Если объем продаж находится между 50-100K, то формула возвращает B2 * 2%, что составляет 2% комиссии в зависимости от объема продажи.

Пример 4. Используем логические операторы (AND/OR) (И/ИЛИ) в функции IF (ЕСЛИ) в Excel

Вы можете использовать логические операторы (AND/OR) (И/ИЛИ) внутри функции для одновременного тестирования нескольких условий.

Например, предположим, что вы должны выбрать студентов для стипендий, основываясь на оценках и посещаемости. В приведенном ниже примере учащийся имеет право на участие только в том случае, если он набрал более 80 баллов и имеет посещаемость более 80%.

Вы можете использовать функцию AND (И) вместе с функцией IF (ЕСЛИ) , чтобы сначала проверить, выполняются ли оба эти условия или нет. Если условия соблюдены, функция возвращает “Имеет право”, в противном случае она возвращает “Не имеет право”.

Формула для этого расчета:

=IF(AND(B2>80,C2>80%),”Да”,”Нет”) — английская версия

=ЕСЛИ(И(B2>80;C2>80%);»Да»;»Нет») — русская версия

Пример 5. Преобразуем ошибки в значения “0” с помощью функции IF (ЕСЛИ)

С помощью этой функции вы также можете убирать ячейки содержащие ошибки. Вы можете преобразовать значения ошибок в пробелы или нули или любое другое значение.

Формула для преобразования ошибок в ячейках следующая:

=IF(ISERROR(A1),0,A1) — английская версия

=ЕСЛИ(ЕОШИБКА(A1);0;A1) — русская версия

Формула возвращает “0”, в случае если в ячейке есть ошибка, иначе она возвращает значение ячейки.

ПРИМЕЧАНИЕ. Если вы используете Excel 2007 или версии после него, вы также можете использовать функцию IFERROR для этого.

Точно так же вы можете обрабатывать пустые ячейки. В случае пустых ячеек используйте функцию ISBLANK, на примере ниже:

=IF(ISBLANK(A1),0,A1) — английская версия

=ЕСЛИ(ЕПУСТО(A1);0;A1) — русская версия

Excel Logical Functions — AND, OR, XOR, NOT

There are many ways to add logical decision-making to your Excel spreadsheets. In addition to the standard logical operators in Excel (=, , <>, =), Excel has compound logical functions which let you evaluate multiple conditions at once. The AND, OR, XOR, and NOT functions in Excel let you evaluate many logical conditions and simply return TRUE or FALSE depending on the function. Because they return TRUE or FALSE, these functions are commonly used with IF functions.

Excel AND Function

The AND function in Excel evaluates one or more logical conditions to determine whether ALL of them are true. It takes one or more conditions as its arguments separated by commas, and returns TRUE if ALL of the conditions are true. Otherwise, it returns FALSE.

=AND(condition_1, [condition_2], . )

The AND function only requires one argument, but can take more (up to 255). The arguments can be conditions, numbers and text, and cell references. If a cell reference argument is empty, the function simply ignores it. If an argument is a number, it will treat zero as FALSE and any non-zero number (even negatives) as TRUE.

=AND(1 «goodbye») evaluates to TRUE because both conditions are true: 1 is less than 2, and «hello» is not equal to «goodbye».

=AND(1 2, 1) is also TRUE. The first argument (1>2) is false, but that’s okay because the second argument (1) is treated as TRUE because it’s not zero. As long as one of the arguments is true, OR will return true.

=OR(1>2, 0) will return FALSE because all of its arguments are false.

Excel XOR Function

The XOR function in Excel is the Exclusive OR function which, like the OR function, takes two conditions and evaluates whether one of them is true. But unlike the OR function, XOR returns TRUE if ONLY ONE argument is true. It returns FALSE if both arguments are true, or if both of the arguments are false. If XOR has more than two arguments, it returns TRUE if an ODD number of its arguments are TRUE, and FALSE if an EVEN number of its arguments are TRUE.

=XOR(condition_1, [condition_2], . )

The XOR function also only requires one argument but can take up to 255 in most recent versions of Excel. Like the AND and OR functions, it can take logical conditions, numbers, text, other logical functions, and cell references as its arguments. If a cell reference is blank, XOR will ignore it, and zero will be treated as FALSE while any non-zero number will be TRUE.

=XOR(1=1, «hello»=»goodbye») will return TRUE because only one argument is true. The first argument (1=1) is obviously true, but the second («hello»=»goodbye») is clearly false. Because only one argument is true, XOR returns TRUE.

=XOR(1=1, «hello» <> «goodbye») returns FALSE because multiple arguments are true. The first (1=1) is true, as is the second because «hello» is not equal to (<>) «goodbye» so XOR will return FALSE. XOR will only return TRUE if ONE of the arguments is true.

=XOR(1=2, «hello»=»goodbye») also returns FALSE because none of the arguments is true. The first (1=2) is false as is the second («hello»=»goodbye»).

Excel NOT Function

The NOT function in Excel is perhaps one of the most simple. It takes a single logical argument and returns TRUE or FALSE. It returns the opposite of the argument, so if the argument is true, NOT will return false, and if the argument is false, NOT will return true.

=NOT(condition)

=NOT(1=1) would return FALSE, because the argument is true.

=NOT(1=2) would return TRUE, because the argument is false.

The NOT function is particularly useful when you’re interested in excluding some property in Excel. For example, say you are looking at a spreadsheet of homes in Excel, and the B column contains the home’s city.

To exclude any homes in Minneapolis, you could write the following function (starting with row 2) and copy it all the way down the column:

=NOT(B2=»Minneapolis»)

This will return TRUE for any home where the city is not Minneapolis, so it will return true for Home 1 and Home 3, but will return false for Home 2.

Combining Logical Functions in Excel

Now imagine you only want to exclude single-family homes in Minneapolis, but keep other home types. City is still in column B, while home type is in column C.

=NOT(AND(B2=»Minneapolis», C2=»Single-Family»))

Because the argument (an AND function) returns TRUE only for single-family homes in Minneapolis, this function will return TRUE for any home that is not a single-family home in Minneapolis. It will return true for Home 1 and Home 3, and will only return false for Home 2.

Combining XOR with AND in Excel

Suppose you love watching new movies, and your favorite movies were made after 2015. Suppose you also love movies that star Will Ferrell and John C. Reilly. But there’s a catch: You hate movies that star Will Ferrell and John C. Reilly that were made after 2015. In the table below, where column B is lead actor, column C is supporting actor, and column D is year, how would you find movies that were made after 2015, and movies with the two co-stars mentioned above, but not movies with the two co-stars made after 2015?

You could use the following formula:

=XOR(AND(B2=»Will Ferrell», C2=»John C. Reilly»), D2>2015)

Step Brothers: TRUE because AND(B2=»Will Ferrell», C2=»John C. Reilly») is TRUE while D2>2015 is FALSE.

Uncut Gems: TRUE because AND(B3=»Will Ferrell», C3=»John C. Reilly») is FALSE while D3>2015 is TRUE.

Anchorman: FALSE because both conditions: AND(B4=»Will Ferrell», C4=»John C. Reilly») as well as D4>2015 are FALSE

Holmes & Watson: FALSE because both conditions are true, thus it is a movie with Will Ferrell and John C. Reilly which was made after 2015.
