értékeljellel

Értékeljellel is a Hungarian term that translates directly to "with a value sign" or "signed value" in English. It is used in various contexts to denote that a number or quantity is accompanied by its sign, indicating whether it is positive or negative. This concept is fundamental in mathematics and programming.

In mathematics, numbers can be positive, negative, or zero. The sign (+ or -) explicitly clarifies this. For example, -5 is a negative number, while +5 or simply 5 is a positive number. When performing calculations, understanding the sign of each number is crucial for obtaining the correct result. Operations like addition and subtraction behave differently depending on the signs of the operands.

In computer science and programming, variables often store numerical values that can be positive or negative. When declaring a variable that is intended to hold a signed value, programmers must specify this. For instance, in many programming languages, an integer data type might be declared as "signed integer" to indicate that it can store both positive and negative whole numbers. Unsigned integers, on the other hand, can only store non-negative values. The use of "értékeljellel" emphasizes the importance of representing and processing these signs accurately in computational processes.
