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

-

-5

*

乘法

2*2

/

除法

9/3

%

百分比

15%

^

乘冪

3^2


note

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。

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.


note

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.


note

Prefix "-" has a higher precedence than "^", "^" is left-associative, and reference intersection has a higher precedence than reference union.


note

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.


note

Precedence can be overridden by using parentheses, so "=2+3*4" computes to 14 but "=(2+3)*4" computes 20.
