ISNA

Returns TRUE if a cell contains the #N/A (value not available) error value.

If an error occurs, the function returns FALSE.

Syntax

ISNA(Value)

Value is the value or expression to be tested.

Example

=ISNA(D3) returns FALSE as a result.

IFERROR

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

tip

This function is available since Collabora Office 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.

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(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.

note

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

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 Collabora Office 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.

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(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.

note

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

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.

tip

This function is available since Collabora Office 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
