## Function name:

IFS

## Category:

Logical

## Summary:

From multiple conditions passed as arguments, determines the first condition that is met and returns the result that corresponds to that condition.

## Syntax:

IFS(**Expression 1**; **Result 1** [; **Expression 2**; **Result 2**][; ... ; [**Expression 127**; **Result 127**]])

## Returns:

Returns a value whose type depends on the nature of the selected result argument.

## Arguments:

**Expression 1**, **Expression 2**, ..., **Expression 127** are expressions, or references to cells containing expressions, that that can be evaluated to a logical value TRUE or FALSE. If an expression is evaluated to a number instead of a logical value, then the value 0 (zero) is treated as FALSE, while any non-zero value is treated as TRUE. Any of Calc’s comparative operators = (equal), <> (inequality), > (greater than), >= (greater than or equal to), < (less than), and <= (less than or equal to) may be used to create conditions in the **Expression n** arguments. Each

**Expression**argument must have a corresponding

*n***Result**argument.

*n***Result 1**, **Result 2**, ..., **Result 127** are expressions, or references to cells containing expressions, that give the results to be returned when the corresponding **Expression n** argument is the first to evaluate to TRUE.

- If an
**Expression**argument cannot be evaluated as a logical value, then IFS reports a #VALUE! error.*n* - If an
**Expression**argument is evaluated as the logical value TRUE but there is no corresponding*n***Result**argument, then IFS reports a #N/A error.*n* - If no
**Expression**argument is evaluated to TRUE, then IFS reports a #N/A error.*n*

## Additional details:

### Details specific to IFS function

- The IFS function can often be used as an easier-to-read alternative to creating a formula using multiple nested IF function calls.

- Unlike the SWITCH function, IFS does not provide a "built-in" default value to use when all other expressions evaluate to false. However, to provide such a default value you can enter TRUE as the final expression, followed by a value to use as a default result.

- The formula
`=IFS(expression1; result1; expression2; result2; expression3; result3)`

is executed as described by the following pseudocode:

- IF expression1 is TRUE
- THEN result1
- ELSE
- IF expression2 is TRUE
- THEN result2
- ELSE
- IF expression3 is TRUE
- THEN result3

- A consequence of this order of execution is that once IFS finds an
**Expression**argument that is true, it evaluates and returns the corresponding*n***Result**argument, without processing any further expression or result arguments. For example, the formula*n*`=IFS(TRUE(); "First result"; 3/0; "Second result")`

returns the string "First result" – while`3/0`

might be expected to generate a #DIV0! error, the division is not attempted in this case.

### General information about Calc's logical functions

Calc uses the numbers 0 (FALSE) and 1 (TRUE) to represent logical values. For example, enter 1 in a cell that has the default general number format. Then select **Boolean Value** option in the *Category* area of the *Numbers* tab, and click the button. Notice that the number 1 is now displayed as TRUE. To revert to displaying the number 1, repeat the process but select **Number** instead of **Boolean Value**.

To enter a logical value into a cell, simply type either TRUE or FALSE (case-insensitive) into the cell. Calc will recognize the logical value, display it in uppercase letters, and change the cell's format to that appropriate to Boolean values.

Calc functions that produce a logical result return a number, either 0 or 1. In the case of a formula that simply calls such a logical function and is in a cell that has the default general number format, the cell is switched to the Boolean value format and the returned value is displayed as FALSE or TRUE. For example `=TRUE()`

returns the value 1, which is displayed as TRUE; if you then change the format to a numerical format, it is displayed as the number 1.

Calc functions that test for a logical result always evaluate the expression to be tested and check if it is equal to 0. The value 0 is taken as FALSE and any other value is taken as TRUE. For example, `=NOT(0)`

returns TRUE and `=NOT(57.89)`

returns FALSE.

In contrast to Calc, Microsoft Excel has a separate type for logical values - they are not numbers but are sometimes converted to numbers. Take care therefore if you need compatibility.

## Examples:

Formula | Description | Returns |
---|---|---|

=IFS(A1>5; 100; A1<=5; "too small") | Here the function returns the number 100 if A1 is greater than 5, and the text "too small" otherwise. The formula `=IF(A1>5; 100; TRUE(); "too small")` is equivalent. |
100 or "too small" |

=IFS(A1=1; "Jan"; A1=2; "Feb"; A1=3; "Mar"; A1=4; "Apr"; A1=5; "May"; A1=6; "Jun"; A1=7; "Jul"; A1=8; "Aug"; A1=9; "Sep"; A1=10; "Oct"; A1=11; "Nov"; A1=12; "Dec") where cell A1 contains the formula =MONTH(TODAY()) and today’s date is 2021-11-28. | The formula extracts the month value from today’s date as an integer and then converts the number to a string giving a three-character abbreviation of the month. | Nov |

=IFS(A1; A2; A3; A4) where cells A1:A4 contain the numbers 0, 123, -1, and 456 respectively. | Here the function evaluates the first argument as false and ignores the second argument. The third argument is evaluated as true and the value 456 is returned. | 456 |
