Sets the number of decimal places that are displayed in the value.
Also causes the value of the adjustment to be rounded to this number of digits, so the retrieved value matches the displayed one, if draw_value is true when the value changes. If you want to enforce rounding the value when draw_value is false, you can set round_digits instead.
Note that rounding to a small number of digits can interfere with the smooth autoscrolling that is built into Scale. As an alternative, you can use the format_value signal to format the displayed value yourself.
