Soulver includes a number of different formatting options for answers.

Default Formatting

You can set your preferred default by going Edit > Tweak Engine > Answers or customize an individual line's formatting through its contextual menu (right or control-click), or through the Line > Formatting Options menu.

If you manually set any 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 going Line > Formatting Options > Use Default Formatting

Decimal Places (dp)

Round your answers to the given decimal places. The default is 10. Change a line's decimal places by either using the Line > Round To menu, or the rounding palette:

Notation

Soulver uses SI Notation to save you counting 0s in the answer. For example, 1,700,000 is rendered as 1.7M.

You can disable this feature by going Line > Display With > Notation for Large/Small numbers.

Fractions

When 'Fractionize where possible' is enabled, the answer's fractional component with be formatted with a fraction where possible. For instance 1.75 will be formatted as 1 3/4 . Not that fractions smaller than 1/100 will not be displayed.
