# Operators in LibreOffice Calc

You can use the following operators in LibreOffice Calc:

## Arithmetical Operators

These operators return numerical results.

Virki

Nafn

Example

+ (Plús)

Bæta við

1+1

- (Mínus)

Frádráttur

2-1

- (Mínus)

Neitun

-5

* (stjarna)

Margföldun

2*2

/ (Skástrik)

Deiling

9/3

% (Prósenta)

Prósenta

15%

^ (ör)

Exponentiation

3^2 Prefix "-" (negation) has a higher precedence than "^" (exponentiation). For example -3^2 equals 9, which is the square of a negative number.

## Samanburðarvirkjar

These operators return either true or false.

Virki

Nafn

Example

= (sama sem merki)

Líkt

A1=B1

> (Stærri en)

Stærri en

A1>B1

< (minna en merki)

Minni en

A1<B1

>= (Stærra en eða jafnt og)

Stærra en eða jafnt og

A1>=B1

<= (Minna en eða jafnt og)

Minna en eða jafnt og

A1<=B1

<> (ekki sama sem)

Ekki sama sem

A1<>B1

## Text operators

The operator combines separate texts into one text.

Stjórnanda

Nafn

Example

& (Og)

text concatenation AND

"Sun" & "day" is "Sunday"

## Reference operators

These operators return a cell range of zero, one or more cells.

Range has the highest precedence, then intersection, and then finally union.

Stjórnanda

Nafn

Example

: (tvípunktur)

Svið

A1:C108

! (Exclamation point)

Skurðflötur

SUM(A1:B6!B5:C12)

Calculates the sum of all cells in the intersection; in this example, the result yields the sum of cells B5 and B6.

~ (Bylgja)

Concatenation or union

Takes two references and returns a reference list, which is a concatenation of the left reference followed by the right reference. Double entries are referenced twice. See note below this table. Reference concatenation using a tilde character was implemented lately. When a formula with the tilde operator exists in a document that is opened in old versions of the software, an error is returned. A reference list is not allowed inside an array expression.
