címtartomány

Címtartomány refers to the range of possible values that a variable or a function can take. In mathematics and computer science, it is a fundamental concept used to define the boundaries and characteristics of data. For a variable, the címtartomány specifies the set of all valid inputs it can accept. For a function, it defines the set of all possible outputs the function can produce for a given domain. Understanding the címtartomány is crucial for correctly interpreting data, preventing errors, and designing efficient algorithms. For example, if a variable represents the age of a person, its címtartomány would typically be non-negative integers. Similarly, a function that calculates the square root of a number will have a címtartomány that includes only non-negative real numbers. Errors can arise if an input outside the defined címtartomány is provided, leading to undefined results or program crashes. In statistics, címtartomány is often referred to as the range of a dataset, which is the difference between the maximum and minimum values. This provides a basic measure of data dispersion.
