Alleenstellige

Alleenstellige is a Dutch adjective meaning having only one digit, i.e., a single-digit number. The term is not standard in formal mathematics or official dictionaries; more common Dutch terms for this concept are éénstellig or ééncijferig. When used, hetinge gewone meaning is descriptive or informal rather than strictly technical.

In practice, alleenstellige getallen refer to integers with a magnitude of less than 10. Depending on the convention, this can include zero and both positive and negative numbers from -9 to 9. A strict interpretation often follows the magnitude criterion absolute value less than 10, so -9 through 9 are considered one-digit numbers. In other contexts, especially in user interfaces or casual writing, the phrase may be used more loosely to indicate any number that does not exceed a single decimal digit.

Usage considerations: because alleenstellige is not widely standardized, it can cause ambiguity. For precise communication, especially in mathematics, programming, or data specifications, it is preferable to use éénstellig or ééncijferig and to state explicitly whether negative values are included. When describing constraints or validation rules, specifying the exact range, such as -9 ≤ x ≤ 9, avoids misinterpretation.
