Ylärajoiltaan

Ylärajoiltaan is Finnish adverb meaning that something is bounded or constrained from above. It is used to describe quantities, parameters, or data sets whose values do not exceed a certain upper limit. The term is most common in technical and scientific contexts such as mathematics, statistics, data analysis, and engineering, where precise boundary specifications are important for describing models, measurements, or constraints.

Ylärajoiltaan is formed from the noun yläraja (upper bound) with the suffix -iltaan, which marks a perspective or aspect of a bound. The corresponding form for lower limits is alarajoiltaan. In Finnish writing, the phrase functions as an adverbial modifier describing how the bound applies—“from the upper bound” or “to the extent of the upper bound.”

Usage examples: “Otosjoukon arvojen yläraja on 100” conveys that the maximum value is 100. “Mittausarvot ovat ylärajoiltaan 50” indicates measurements do not exceed 50. In programming or data-validation contexts, one might specify that inputs are ylärajoiltaan rajoitettu arvoon 10.

Limitations: because it is a technical term, ylärajoiltaan is primarily found in written Finnish rather than colloquial speech, and may appear in reports, specifications, or academic texts. The concept is closely related to the idea of an upper bound (yläraja).
