# Функтсияҳои мантиқӣ

This category contains the Logical functions.

### Handling non-logical arguments in logical functions

- Zero (0) is equivalent to FALSE and all other numbers are equivalent to TRUE.

- Empty cells and text in cells are ignored.

- A #VALUE error is raised if all arguments are ignored.

- A #VALUE error is raised if one argument is direct text (not text in a cell).

- Errors as argument lead to an error.

### ISNA

ҲАҚҚОНӢ-ро бармегардонад агар чашмак #N/A дошта бошад.

If an error occurs, the function returns FALSE.

#### Syntax

ISNA(Value)

Value арзиши санҷидашаванда.

#### Example

ISNA(D3) ҚАЛБАКӢ-ро бармегардонад.

### IFERROR

Returns the value if the cell does not contain an error value, or the alternative value if it does.

This function is available since LibreOfficeDev 4.0.

#### Syntax

IFERROR(Value; Alternate_value)

Value is the value or expression to be returned if it is not equal or results in an error.

Alternate_value is the value or expression to be returned if the expression or value of Value is equal or results in an error.

#### Example

=IFERROR(C8;C9) where cell C8 contains =1/0 returns the value of C9, because 1/0 is an error.

=IFERROR(C8;C9) where cell C8 contains 13 returns 13, the value of C8, which is not an error.

## IFS

IFS is a multiple IF-function.

## SWITCH

SWITCH compares expression with value1 to valuen and returns the result belonging to the first value that equals expression. If there is no match and default_result is given, that will be returned.

## NOT

Арзиши мантиқиро баръакс мегардонад.

#### Syntax

NOT(LogicalValue)

Logical Value арзиши баргардонидашаванда.

#### Example

NOT(A). A=ҲАҚҚОНӢ ба A=ҚАЛБАКӢ баргардонида мешавад.

## XOR

Returns true if an odd number of arguments evaluates to TRUE.

Аргументҳо худашон ифодаи мантиқианд (TRUE, 1<5, 2+3=7, B8<10) ки арзиши мантиқӣ медиҳанд ё массив (A1:C3) ки арзиши мантиқӣ дорад.

This function is available since LibreOfficeDev 4.0.

#### Syntax

XOR(Logical 1 [; Logical 2 [; … [; Logical 255]]])

Logical 1; Logical 2; … ; Logical 255 are boolean values, references to cells or to cell ranges of logical values.

#### Example

=XOR(TRUE();TRUE()) returns FALSE

=XOR(TRUE();TRUE();TRUE()) returns TRUE

=XOR(FALSE();TRUE()) returns TRUE

## Ё

ҲАҚҚОНӢро бармегардонад агар ақалан як арзиш ҲАҚҚОНӢ бошад.

Аргументҳо худашон ифодаи мантиқианд (TRUE, 1<5, 2+3=7, B8<10) ки арзиши мантиқӣ медиҳанд ё массив (A1:C3) ки арзиши мантиқӣ дорад.

#### Syntax

OR(Logical 1 [; Logical 2 [; … [; Logical 255]]])

Logical 1; Logical 2; … ; Logical 255 are boolean values, references to cells or to cell ranges of logical values.

This function ignores any text or empty cell within a data range. If you suspect wrong results from this function, look for text in the data ranges. To highlight text contents in a data range, use the value highlighting feature.

#### Example

Арзиши мантиқии 12<11; 13>22, ва 45=45 санвида мешаванд.

OR(12<11; 13>22; 45=45) натиҷа ҲАҚҚОНӢ.

=OR(FALSE();TRUE()) returns TRUE.

The array formula {=OR(B1:B10;C1:C10)} yields a one-dimensional value of FALSE when all components of B1:B10 and C1:C10 are FALSE. The array expression above does not produce the logical OR per element, and thus does not produce an array of logical values. To compute a logical OR of arrays per element use the + operator in array context. In the example, enter {=B1:B10+C1:C10}.

## АГАР

Санҷиши мантиқӣ мегузаронад.

#### Syntax

IF(Test [; [ThenValue] [; [OtherwiseValue]]])

Testарзиш ё ифода, ки ҲАҚҚОНӢ ё ҚАЛБАКӢ мебошад.

Then_value (optional) арзишест, ки ҳангоми ҲАҚҚОНӢ будани натиҷа баргардонида мешавад.

Otherwise_value (ихтиёрӣ) арзишест, ки ҳангоми ҚАЛБАКӢ будани натиҷа баргардонида мешавад.

In the LibreOfficeDev Calc functions, parameters marked as "optional" can be left out only when no parameter follows. For example, in a function with four parameters, where the last two parameters are marked as "optional", you can leave out parameter 4 or parameters 3 and 4, but you cannot leave out parameter 3 alone.

#### Example

=IF(A1>5;100;"too small") If the value in A1 is greater than 5, the value 100 is returned; otherwise, the text too small is returned.

=IF(A1>5;;"too small") If the value in A1 is greater than 5, the value 0 is returned because empty parameters are considered to be 0; otherwise, the text too small is returned.

=IF(A1>5;100;) If the value in A1 is less than 5, the value 0 is returned because the empty OtherwiseValue is interpreted as 0; otherwise 100 is returned.

## ВА

ҲАҚҚОНӢро бармегардонад, агар ҳама аргументҳо ҲАҚҚОНӢ бошанд.

Аргументҳо худашон ифодаи мантиқианд (TRUE, 1<5, 2+3=7, B8<10) ки арзиши мантиқӣ медиҳанд ё массив (A1:C3) ки арзиши мантиқӣ дорад.

#### Syntax

AND(Logical 1 [; Logical 2 [; … [; Logical 255]]])

Logical 1; Logical 2; … ; Logical 255 are boolean values, references to cells or to cell ranges of logical values.

This function ignores any text or empty cell within a data range. If you suspect wrong results from this function, look for text in the data ranges. To highlight text contents in a data range, use the value highlighting feature.

#### Example

Арзишҳои мантиқии 12<13; 14>12 ва 7<6 санҷида мешаванд:

AND(12<13; 14>12; 7<6) натиҷа ҚАЛБАКӢ.

=AND(FALSE();TRUE()) returns FALSE.

The array formula {=AND(B1:B10;C1:C10)} yields a one-dimensional value of TRUE when all components of B1:B10 and C1:C10 are TRUE. The array expression above does not produce the logical AND per element, and thus does not produce an array of logical values. To compute a logical AND of arrays per element use the * operator in array context. In the example, enter {=B1:B10*C1:C10}.

## ҚАЛБАКӢ

Натиҷа ҚАЛБАКӢ бармегардонад. Функтсияи FALSE() аргумент қабул намекунад ва доим ҚАЛБАКӢ аст.

#### Syntax

FALSE()

#### Example

FALSE() натиҷа FALSE

NOT(FALSE()) натиҷа TRUE

## ҲАҚҚОНӢ

Арзиши мантиқӣ ба ҲАҚҚОНӢ табдил мешавад. Функтсияи TRUE() ягон аргумент намегирад.

#### Syntax

TRUE()

#### Example

Агар A=ҲАҚҚОНӢ ва B=ҚАЛБАКӢ бошад, онгоҳ:

=AND(A;B) натиҷа ҚАЛБАКӢ.

=OR(A;B) натиҷа ҲАҚҚОНӢ.

=NOT(AND(A;B)) натиҷа ҲАҚҚОНӢ.
