# Operatorer i LibreOffice Calc

Du kan använda följande operatorer i LibreOffice Calc:

## Aritmetiska operatorer

Dessa operatorer ger numeriska resultat.

Operator

Namn

Example

+

1+1

-

Subtraktion

2-1

-

Negation

-5

*

Multiplikation

2*2

/

Division

9/3

%

Procent

15%

^

Exponent

3^2

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

## Relationsoperatorer

Dessa operatorer ger det logiska värdet SANT eller FALSKT.

Operator

Namn

Example

=

Lika med

A1=B1

>

Större än

A1>B1

<

Mindre än

A1<B1

>=

Större än eller lika med

A1>=B1

<=

Mindre än eller lika med

A1<=B1

<>

Inte lika med

A1<>B1

## Textoperator

Operatorn länkar enskilda texter till en hel text.

Operator

Namn

Example

&

text concatenation

"Sun" & "day" returnerar "Sunday"

## Referensoperatorer

Operatorerna returnerar ett cellområde utan celler eller med en eller flera celler.

Område har den högsta prioriteten, sedan skärningspunkt och därefter union.

Operator

Namn

Example

:

Område

A1:C108, A:D or 3:13

!

Snitt

SUMMA(A1:B6!B5:C12)

Här ligger cellerna B5 och B6 i snittet och deras summa beräknas.

~

Länkning eller 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.

=COUNT(A1:B2~B2:C3) counts values of A1:B2 and B2:C3. Note that the cell B2 is counted twice.

=INDEX(A1:B2~C1:D2;2;1;2) selects cell C2, that is, the first cell of the second row, first column, of the second range (C1:D2) of the range list.

A reference list is not allowed inside an array expression.

## Operator precedence

Associativity and precedence of operators, from highest to lowest precedence.

Associativity

Operator(s)

left

:

Range.

left

!

Reference intersection (A1:C4!B1:B5 is B1:B4).

left

~

Reference union.

right

+,-

Prefix unary operators. For example, -5 or -A1. Note that these have a different precedence than add and subtract.

left

%

Postfix unary operator % (divide by 100). Note that this is legal with expressions, for example, B1%.

left

^

Power (2^3 is 8).

left

*,/

Multiply, divide.

left

+,-

Binary operations add, subtract. Note that unary (prefix) + and - have a different precedence.

left

&

Binary operation string concatenation. Note that "&" shall be escaped when included in an XML document.

left

=, <>, <, <=,
>, >=

Comparison operators equal to, not equal to, less than, less than or equal to, greater than, greater than or equal to.

Prefix "-" has a higher precedence than "^", "^" is left-associative, and reference intersection has a higher precedence than reference union.

Prefix "+" and "-" are defined to be right-associative. However, note that typical applications which implement at most the operators defined in this specification (as specified) may implement them as left-associative, because the calculated results will be identical.

Precedence can be overridden by using parentheses, so "=2+3*4" computes to 14 but "=(2+3)*4" computes 20.
