Number formats

Regional presets, thousands separators, compact notation, and decimal-comma handling.

Numlex formats both what you type and what it answers so numbers read the way your region expects. Settings live on the Numbers tab (Settings → Numbers).

Regional presets

Four presets control digit grouping, decimal separator and related behavior:

PresetLocaleDecimalGrouping
Systemfollows macOS. or ,locale default
North Americaen_US.1,234.5
Western Europede_DE,1.234,5
Eastern Europeru_RU,1 234,5

Choose System to track whatever the rest of your Mac uses.

Toggles

Three independent switches refine any preset:

  • Convert foreign numbers on paste — re-interpret pasted figures that use a different separator convention.
  • Thousands separator — show (or hide) the grouping mark in answers.
  • Compact notation — render large magnitudes compactly.

Decimal-comma modes

When a preset uses a comma as the decimal separator (Western Europe, Eastern Europe, or a comma-decimal System locale), a comma can no longer serve as a thousands or argument separator. In these modes Numlex uses a semicolon ; as the list separator inside function calls, so arguments stay unambiguous:

sum(1; 234)        two arguments: 1 and 234
average(4; 8)       6

In dot-decimal presets the ordinary comma rules apply instead — including the thousands-separator nuance described in Variables & functions.
