Numeric grouping and decimal separators

Understand the principle

Separators can indicate decimal fractions or digit groups under different conventions. A visual inconsistency may be an error or deliberately retained source data. Locale-specific expectations and the publication’s own standard must be considered together.

Look in Typography. The publication concept and a plugin issue identifier are related, but are not interchangeable.

Compare the intent, not only the characters

1,234.56 beside 1.234,56

One intended presentation, with the original values retained.

Schematic teaching example, not a plugin screenshot or a promise of automatic correction.

Review it in Avellio 2.0

Verify the source value and selected policy before replacing punctuation. Review tables and footnotes separately where coverage is limited. After an edit, compare the displayed value with the source and inspect composition. Read Found and Suggested when offered, or Review in context. Check Text locale; the recommendation itself changes no text. After an intentional manual edit, inspect again.

Use the selected finding’s actual evidence and offered actions. If no suitable supported action exists, make a justified manual decision in InDesign or retain the occurrence. After an edit, inspect again and check nearby composition.

When the difference can be intentional

Identifiers, code and mixed-language data can require literal preservation. Matching formatting does not establish factual numeric accuracy.
