# Operátory v LibreOffice Calc

V LibreOffice Calc je možné používať následujúce operátory:

## Aritmetické operátory

Tieto operátory vrátia numerické výsledky.

Operátor | Názov | Príklad
--- | --- | ---
+ | Sčítanie | 1+1
- | Odčítanie | 2-1
- | Negácia | -5
* | Násobenie | 2*2
/ | Delenie | 9/3
% | Percento | 15%
^ | Umocnenie | 3^2

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

## Porovnávacie operátory

Tieto operátory vrátia buď hodnotu pravda alebo nepravda.

Operátor | Názov | Príklad
--- | --- | ---
= | Rovno | A1=B1
> | väčšie ako | A1>B1
< | menšie ako | A1<B1
>= | väčšie alebo rovné | A1>=B1
<= | menšie alebo rovné | A1<=B1
<> | Nerovná sa | A1<>B1

## Textové operátory

Operátor spojí oddelené textové reťazce do jedného.

Operátor | Názov | Príklad
--- | --- | ---
& | text concatenation | "Auto" & "škola" je "Autoškola"

## Referenčné operátory

Tieto operátory vrátia oblasť buniek - žiadnu, jednobunkovú alebo viac bunkovú.

Oblasť má najvyššiu prioritu, potom priesečník a nakoniec spojenie.

Operátor | Názov | Príklad
--- | --- | ---
: | Oblasť | A1:C108, A:D or 3:13
! | Prienik | SUM(A1:B6!B5:C12) Vypočíta súčet všetkých buniek v prieniku. V danom príklade bude výsledok súčet buniek B5 a B6.
~ | Zreťazenie alebo spojenie | 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) | Poznámky
--- | --- | ---
vľavo | : | Range.
vľavo | ! | Reference intersection (A1:C4!B1:B5 is B1:B4).
vľavo | ~ | Reference union.
doprava | +,- | Prefix unary operators. For example, -5 or -A1. Note that these have a different precedence than add and subtract.
vľavo | % | Postfix unary operator % (divide by 100). Note that this is legal with expressions, for example, B1%.
vľavo | ^ | Power (2^3 is 8).
vľavo | *,/ | Multiply, divide.
vľavo | +,- | Binary operations add, subtract. Note that unary (prefix) + and - have a different precedence.
vľavo | & | Binary operation string concatenation. Note that "&" shall be escaped when included in an XML document.
vľavo | =, <>, <, <=, >, >= | 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.
