# LibreOffice Calc 中的运算符

您可以在 LibreOffice Calc 中使用以下运算符:

## 算术运算符

这些运算符返回数字结果。

运算符 | 名称 | Example
--- | --- | ---
+ | 加法 | 1+1
- | 减法 | 2-1
- | 非 | -5
* | 乘法 | 2*2
/ | 除法 | 9/3
% | 百分比 | 15%
^ | 乘方 | 3^2

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

B^X may or may not report a #NUM! error when B is negative and X is not an integer. The expression =B^X is calculated the same way as =POWER(B;X).

## 比较运算符

这些运算符返回逻辑值 TRUE 或 FALSE。

运算符 | 名称 | Example
--- | --- | ---
= | 等于 | A1=B1
> | 大于 | A1>B1
< | 小于 | A1<B1
>= | 大于或等于 | A1>=B1
<= | 小于或等于 | A1<=B1
<> | 不等于 | A1<>B1

## 文字运算符

该运算符把各文本合并到一个文本中。

运算符 | 名称 | Example
--- | --- | ---
& | text concatenation | "Sun" & "day"得出"Sunday"

## 引用运算符

这些运算符返回 0、1 或更多个单元格区域。

区域具有最高优先级，然后是交集，最后是并集。

运算符 | 名称 | Example
--- | --- | ---
: | 区域 | A1:C108, A:D or 3:13
! | 交集 | SUM(A1:B6!B5:C12) 计算交集中所有单元格的和。此例中，计算单元格 B5 和 B6 的和。
~ | 连接或并集 | 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.
