Soulver includes a number of different formatting options for answers.
You can set the default formatting preferences by going Settings > Calculator > Answer Formatting or customize an individual line's formatting through the contextual menu (control-click on the answer), or with the Format menu.
If you manually set formatting options on a line, it will no longer "sync" with the default formatting options. You can reset a line's formatting to match & sync with the defaults by goingFormat > Reset to Defaults
Decimal Places (dp)
Change the number of decimal places shown in an answer using the Format > Precision menu, or with the contextual menu:
Setting decimal places via the contextual menu
Rounding formatting is only cosmetic. The maximum accuracy unrounded answer will be used in subtotals and line references.
Soulver uses SI Notation. For example, 1,700,000 is expressed as 1.7M.
If you need to see the entire number, you can disable this feature for a single line in the contextual menu on an answer. Or disable it completely for all lines in the Calculator >Answer Formatting preferences.
With currency rounding on (the default), currencies will be auto-rounded to their preferred number of decimal places. For most currencies this is 2 dp, though there are currencies like Japanese Yen that round to 0 dp.
Unlike regular lines, the rounded answer of currencies is used in subtotals and line references. This matches how money works in the real world.
You should disable currency rounding if you need sub-cent accuracy.

An exception to this is when using variables, which always use unrounded answers, even of currency lines.
You may want to manually round a currencies in a variable as shown below, or use a line reference instead.
Line references use the rounded currency value, variables do not.
