AND

Returns TRUE if all arguments are TRUE. If one of the elements is FALSE, this function returns the FALSE value.

The arguments are either logical expressions themselves (TRUE, 1<5, 2+3=7, B8<10) that return logical values, or arrays (A1:C3) containing logical values.

Syntax

AND(LogicalValue1; LogicalValue2 ...LogicalValue30)

LogicalValue1; LogicalValue2 ...LogicalValue30 are conditions to be checked. All conditions can be either TRUE or FALSE. If a range is entered as a parameter, the function uses the value from the range that is in the current column or row. The result is TRUE if the logical value in all cells within the cell range is TRUE.

Example

The logical values of entries 12<13; 14>12, and 7<6 are to be checked:

=AND(12<13;14>12;7<6) returns FALSE.

=AND (FALSE;TRUE) returns FALSE.

FALSE

Returns the logical value FALSE. The FALSE() function does not require any arguments, and always returns the logical value FALSE.

Syntax

FALSE()

Example

=FALSE() returns FALSE

=NOT(FALSE()) returns TRUE

IF

Specifies a logical test to be performed.

Syntax

IF(Test; ThenValue; OtherwiseValue)

Test is any value or expression that can be TRUE or FALSE.

ThenValue (optional) is the value that is returned if the logical test is TRUE.

OtherwiseValue (optional) is the value that is returned if the logical test is FALSE.

In the LibreOffice 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.

Examples

=IF(A1>5;100;"too small") If the value in A1 is higher than 5, the value 100 is entered in the current cell; otherwise, the text “too small” (without quotes) is entered.

NOT

Complements (inverts) a logical value.

Syntax

NOT(LogicalValue)

LogicalValue is any value to be complemented.

Example

=NOT(A). If A=TRUE then NOT(A) will evaluate FALSE.

OR

Returns TRUE if at least one argument is TRUE. This function returns the value FALSE, if all the arguments have the logical value FALSE.

The arguments are either logical expressions themselves (TRUE, 1<5, 2+3=7, B8<10) that return logical values, or arrays (A1:C3) containing logical values.

Syntax

OR(LogicalValue1; LogicalValue2 ...LogicalValue30)

LogicalValue1; LogicalValue2 ...LogicalValue30 are conditions to be checked. All conditions can be either TRUE or FALSE. If a range is entered as a parameter, the function uses the value from the range that is in the current column or row.

Example

The logical values of entries 12<11; 13>22, and 45=45 are to be checked.

=OR(12<11;13>22;45=45) returns TRUE.

=OR(FALSE;TRUE) returns TRUE.

TRUE

The logical value is set to TRUE. The TRUE() function does not require any arguments, and always returns the logical value TRUE.

Syntax

TRUE()

Example

If A=TRUE and B=FALSE the following examples appear:

=AND(A;B) returns FALSE

=OR(A;B) returns TRUE

=NOT(AND(A;B)) returns TRUE

XOR

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

The arguments are either logical expressions themselves (TRUE, 1<5, 2+3=7, B8<10) that return logical values, or arrays (A1:C3) containing logical values.

Syntax

XOR(LogicalValue1; LogicalValue2 ...LogicalValue30)

Example

=XOR(TRUE;TRUE) returns FALSE

=XOR(TRUE;TRUE;TRUE) returns TRUE

=XOR(FALSE;TRUE) returns TRUE
