LibreOffice 25.2 ヘルプ
LibreOffice Calc では、次の演算子が使用できます:
この演算子は、計算結果として数値を返します。入力は常に半角で行います。
| 演算子 | 名前 | 例 | 
|---|---|---|
| + | 加算 | 1+1 | 
| - | 減算 | 2-1 | 
| - | 負の数 | -5 | 
| * | 乗算 | 2*2 | 
| / | 除算 | 9/3 | 
| % | パーセント | 15% | 
| ^ | べき算 | 3^2 | 
Prefix "-" (negation) has a higher precedence than "^" (exponentiation). For example -3^2 equals 9, which is the square of a negative number.
この演算子は、計算結果として TRUE または FALSE を返します。入力は常に半角で行います。
| 演算子 | 名前 | 例 | 
|---|---|---|
| = | 等しい | A1=B1 | 
| > | 左辺が右辺よりも大きい | A1>B1 | 
| < | 左辺が右辺よりも小さい | A1<B1 | 
| >= | 左辺が右辺以上 | A1>=B1 | 
| <= | 左辺が右辺以下 | A1<=B1 | 
| <> | 左辺と右辺が等しくない | A1<>B1 | 
この演算子は、文字列どうしを結合します。入力は常に半角で行います。
| 演算子 | 名前 | 例 | 
|---|---|---|
| & | text concatenation | "Sun" & "day" は Sunday を返します。 | 
これらの演算子は、ゼロ、または 1 つ以上のセルのセル範囲を返します。
範囲が優先順位がもっとも高く、次が積集合で、最後が和集合です。
| 演算子 | 名前 | 例 | 
|---|---|---|
| : | 範囲 | A1:C108, A:D or 3:13 | 
| ! | 共通部分 | SUM(A1:B6!B5:C12) この場合、セル B5 とセル B6 が共通部分にあり、合計が計算されます。 | 
| ~ | 連結または結合 | 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) | コメント | 
|---|---|---|
| 左へ | : | Range. | 
| 左へ | ! | Reference intersection (A1:C4!B1:B5 is B1:B4). | 
| 左へ | ~ | Reference union. | 
| 右へ | +,- | Prefix unary operators. For example, -5 or -A1. Note that these have a different precedence than add and subtract. | 
| 左へ | % | Postfix unary operator % (divide by 100). Note that this is legal with expressions, for example, B1%. | 
| 左へ | ^ | Power (2^3 is 8). | 
| 左へ | *,/ | Multiply, divide. | 
| 左へ | +,- | Binary operations add, subtract. Note that unary (prefix) + and - have a different precedence. | 
| 左へ | & | Binary operation string concatenation. Note that "&" shall be escaped when included in an XML document. | 
| 左へ | =, <>, <, <=, | 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.
