Number Format

Choose how results are grouped and how decimals are separated in Settings → Keyboard → Special Keys → Calculator (*) → Number format:

FormatExample
Dot grouping, comma decimal1.234,56
Comma grouping, dot decimal1,234.56
Space grouping, comma decimal1 234,56

Each option shows a live preview (e.g. 96 × 35 = 3.360) so you can see exactly how results will look. The decimal key on the keypad also follows this setting.

info You can also type quick math expressions directly into the Universal Smart Search bar — Calculator Mode is the keypad-first alternative optimized for one-handed use.
