| * the uppercase ''S'' following the last ''#'' or ''0'' indicates the presence of a separator. By default the separator is spaced every 3 digits, but that can be controlled by including the number of digits in each group immediately following the ''S''; for example ''"S4"'' will add the fractional separator every 4 digits. Valid values for ''S'' are ''1'' through ''15'', and the separator character used will be as defined by the command ''[[manual:chapter6:flags:cmd_setlocale|SETLOCALE]]''.\\ **NOTE**: the number of digits in a group must match between the integer and fractional part of the number, it's an invalid format string to request separators every //n// digits on the integer part, and //m// digits on the fractional part when //m≠n//. | * the uppercase ''S'' following the last ''#'' or ''0'' indicates the presence of a separator.

| **newRPL** provides a certain number of preset formats which can be quickly accessed via the keyboard: | A different, user friendly way to change the display of numbers is to use the preset formats that are provided by **newRPL**. These presets are quickly accessed via the keyboard and can be combined in many different ways: |
| |
| * **ON<sup>hold</sup>-SP** cycles thru number format presets; | * **ON<sup>hold</sup>-SP** cycles thru number format presets; |
| * **ON<sup>hold</sup>-DT** cycles thru localization presets; | * **ON<sup>hold</sup>-DOT** cycles thru localization presets; |
| * **ON<sup>hold</sup>-{1...9}** selects the length of the fractional part in scientific or engineering mode. | * **ON<sup>hold</sup>-{1...9}** selects the length of the fractional part in scientific or engineering mode; |
| | * **ON<sup>hold</sup>-{MUL/DIV}** switches to engineering mode and selects ''Auto'' (no preferred exponent) or a preferred exponent in the range ''-21'' to ''21'' in steps by 3. |
