Translation guide
In mathematics and computing, an operand is a value or variable that an operator acts on. This guide covers how to express this concept in Japanese, from technical terms to everyday explanations.
The formal term for a value or variable that an operator acts upon, used in mathematics, programming, and logic.
The most common and direct translation, a katakana loanword from English. Widely used in computing and mathematics.
加算演算子のオペランドは数値でなければなりません。
The operands of the addition operator must be numeric.
A more formal, kanji-based term. Literally 'operated-upon element'. Used in academic or technical writing.
この演算子は二つの被演算子を取ります。
This operator takes two operands.
Literally 'operation number'. Less common, but sometimes seen in older or translated texts.
演算数をスタックにプッシュします。
Push the operand onto the stack.
When you need to describe what an operand is to someone unfamiliar with the term, using everyday language.
A clear, descriptive phrase meaning 'the value that is the target of an operation'. Suitable for explanations.
オペランドとは、演算の対象となる値のことです。
An operand is the value that is the target of an operation.
Another descriptive phrase: 'the value that the operator acts on'. Slightly more technical.
演算子が作用する値をオペランドと呼びます。
The value that an operator acts on is called an operand.
In most technical contexts, オペランド is perfectly understood. Use 被演算子 for formal documents or when you want to avoid loanwords. In casual conversation, you might just explain the concept with a phrase like 計算に使う値 (the value used in the calculation).
