# LibreOffice Calc 中的運算子

在 LibreOffice Calc 中您可以使用以下運算子：

## 直線運算子

這些運算子提供數字結果。

運算子 | 名稱 | Example
--- | --- | ---
+ | 加法 | 1+1
- | 減法 | 2-1
- | 負 | -5
* | 乘法 | 2*2
/ | 除法 | 9/3
% | 百分比 | 15%
^ | 乘冪 | 3^2

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

## 比較運算子

這些運算子提供布氏值 TRUE 或 FALSE。

運算子 | 名稱 | Example
--- | --- | ---
= | 等於 | A1=B1
> | 大於 | A1>B1
< | 小於 | A1<B1
>= | 大於或等於 | A1>=B1
<= | 小於或等於 | A1<=B1
<> | 不等於 | A1<>B1

## 文字運算子

文字運算子會將個別文字連結為集體文字。

運算子 | 名稱 | Example
--- | --- | ---
& | text concatenation | "Sun" & "day" 得出 "Sunday"

## 參照運算子

這些運算子會傳回零個、一個或多個儲存格的儲存格範圍。

範圍具有最高等級的優先順序，接著是交集，最後才是併集。

運算子 | 名稱 | Example
--- | --- | ---
: | 區域 | A1:C108, A:D or 3:13
! | 平均數集合 | SUM(A1:B6!B5:C12) 在此，儲存格 B5 和 B6 會位於平均數集合中，並計算出它們的總和。

連結或併集

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) | 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.
