English uses, respectively, a comma and full stop for grouping and decimals (for example, 1,000.00), but if you’re working in a language that uses something different, you can adjust the relevant settings here; similarly, currency and its relevant grouping/decimal options, can be defined, along with default measurement units for the system (Metric or US).
