LibreOffice 25.8 Help
在 LibreOffice Calc 中您可以使用以下運算子:
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.
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" | 
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.
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.
