Felezés

Felezés is the process of dividing something into two equal parts; the resulting pieces are halves. The term comes from the Hungarian word fél meaning half, with the agent-forming suffix -ezés indicating an action or process.

In mathematics, felezés is division by two. For any number x, the halved value is x/2. Halving is the inverse operation of doubling. In integer arithmetic, dividing by two yields the floor of x/2 for nonnegative integers, and in binary representation, halving corresponds to a right-shift by one bit.

In measurement and geometry, halving a length halves that dimension. Halving multiple dimensions affects area and volume according to the usual geometric rules: halving one dimension halves the length, while halving all dimensions of a shape reduces area to a quarter and volume to an eighth, assuming uniform scaling.

In everyday language, felezés describes cutting quantities, portions, or resources into two equal parts, such as halving a recipe or a budget item. In computing and algorithms, halving is used to reduce a search interval by about half, as in binary search, or to partition data.

In data handling and statistics, felezés can refer to splitting data into two halves for testing, validation, or staged experiments. The concept is a general mathematical and practical operation found across disciplines, often associated with notions of balance, symmetry, and proportional reduction.
