Operadores no LibreOffice Calc
Pode utilizar os seguintes operadores no LibreOffice Calc:
Operadores aritméticos
Estes operadores devolvem resultados numéricos.
|
Operador |
Nome |
Example |
|---|---|---|
|
+ |
Adição |
1+1 |
|
- |
Subtração |
2-1 |
|
- |
Negação |
-5 |
|
* |
Multiplicação |
2*2 |
|
/ |
Divisão |
9/3 |
|
% |
Percentagem |
15% |
|
^ |
Exponenciação |
3^2 |
Prefix "-" (negation) has a higher precedence than "^" (exponentiation). For example -3^2 equals 9, which is the square of a negative number.
Operadores comparativos
Estes operadores devolvem o valor verdadeiro ou falso.

|---|---|---|
|
= |
Igual |
A1=B1 |
|
> |
Maior que |
A1>B1 |
|
< |
Menor que |
A1<B1 |
|
>= |
Maior ou igual a |
A1>=B1 |
|
<= |
Menor ou igual a |
A1<=B1 |
|
<> |
Desigualdade |
A1<>B1 |
Operadores de texto
O operador combina textos distintos num único texto.
|
Operador |
Nome |
Example |
|---|---|---|
|
& |
text concatenation |
"Giras" & "sol" corresponde a "Girassol" |
Operadores de referências
Estes operadores devolvem um intervalo de células de zero, uma ou mais células.
O intervalo tem a maior precedência, em seguida, interseção e, por último, união.
|
Operador |
Nome |
Example |
|---|---|---|
|
: |
Intervalo |
A1:C108, A:D or 3:13 |
|
! |
Interseção |
SOMA(A1:B6!B5:C12) Calcula a soma de todas as células na interseção. Neste exemplo, o resultado devolve a soma das células B5 e B6. |
|
~ |
Concatenação ou união |
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.

Operator(s) |
Comments |
|---|---|---|
|
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.
