The paper discusses the concept of non-exactness of measurement results, and analyzes it by clearly distinguishing between: (i) the way the results are expressed to make their uncertainty explicit; (ii) the way the chosen expression is interpreted as a suitable combination of non-specificity and uncertainty; (iii) the way the interpreted results are formally dealt with. In this perspective the merits and flaws of the ISO Guide to the expression of uncertainty in measurement are highlighted.
