Lähendatav

Lähendatav is an Estonian adjective meaning that something can be approximated or estimated, typically within a chosen level of accuracy. It is used in mathematical, statistical, and computing contexts to describe quantities, results, or models that do not have an exact value but can be obtained by approximation methods.

Etymology and formation: The word derives from the verb lähendama, meaning to bring closer or to approximate, with the suffix -atav forming an adjective that indicates capability or possibility. In usage, it characterizes objects or problems that admit a near representation rather than a precise one.

Usage and contexts: Lähendatav is commonly applied in numerical analysis, data analysis, and related fields to distinguish between exact and approximate quantities. It often appears together with expressions like lähendatava väärtus (an approximable value), lähenduste meetod (an approximation method), or lähendatava vea piir (the bound of approximation error). The term helps emphasize tolerance, error margins, and practical computability when exact solutions are unattainable or impractical.
