LibreOffice Calc で使える演算子
LibreOffice Calc では、次の演算子が使用できます:
算術演算子
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 |
Example |
|---|---|---|
|
+ |
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.
比較演算子
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 |
Example |
|---|---|---|
|
= |
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 |
文字列演算子
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 |
Example |
|---|---|---|
|
& |
text concatenation |
"Sun" & "day" は Sunday を返します。 |
参照演算子
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 |
Example |
|---|---|---|
|
: |
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.
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.
