fraktsionaalseid

Fraktsionaalseid is an Estonian adjective meaning fractional, used to describe quantities, measurements, or values that are not whole numbers. In mathematical and scientific contexts it denotes parts or values that lie between whole units and can be expressed as fractions, decimals, or other non-integer forms.

In mathematics the term fraktsionaalseid typically refers to non-integer numbers. This includes fractions expressed as ratios, decimal representations, and also irrational numbers. The concept is contrasted with whole numbers, which are integers without fractional parts. The language often appears in phrases such as fraktsionaalseid osi (fractional parts), fraktsionaalseid koefitsiente (fractional coefficients), or fraktsionaalseid arve (fractional values).

A common related notion is the fractional part of a real number. For any real number x, the fractional part {x} is x minus the greatest integer not exceeding x, and it lies in the interval [0, 1). The fractional part is widely used in modular arithmetic, computer science, and numerical analysis, as well as in problems dealing with periodicity or remainders.

In applied contexts, fraktsionaalseid quantities appear in measurements, economics, and statistics, where precision is often expressed with fractions or decimals rather than counting whole units. Rounding, truncation, and approximation are typical techniques when working with fraktsionaalseid values to suit practical requirements.
