íselné

Íselné is a form that appears in Slovak and Czech texts as an adjective meaning numeric or related to numbers. In standard spelling, the corresponding adjective is číselný, with inflected forms such as číselné used before certain nouns (for example, číselné údaje). The root čísl- comes from číslo, meaning number, and the suffix -ný turns it into an adjective meaning “numerical.” The form íselné is generally considered nonstandard or a variant that can arise from typographical errors, dialectal spellings, or OCR misreads where the initial č is rendered as i.

In usage, číselné (and by extension its variants) describes data, systems, or representations that involve numbers. Typical contexts include numeric data (číselné údaje), numeric digits (číselné znaky), or numeral systems (číselné systémy). The term is common in mathematics, statistics, computer science, and data processing, where quantities, counts, and numeric representations are central.

Relation to other terms: in English, the equivalent is numeric or numerical. The Slovak and Czech vocabulary also distinguishes číselný (masculine), číselná (feminine), and číselné (neuter/plural) forms according to gender and grammatical case. While íselné can be encountered in some texts, speakers and writers typically use číselné in standard language.

Summary: íselné is a nonstandard or variant form used to mean numeric or numerical in Slovak and Czech, with the standard form číselný and its inflections. It is employed to describe things involving numbers, such as data, digits, and numeral systems, in technical and mathematical contexts.
