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.
比较运算符
这些运算符返回逻辑值 TRUE 或 FALSE。
|

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.

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.
