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 #GtkScale:draw-value is
%TRUE when the value changes. If you want to enforce rounding the value when
#GtkScale:draw-value is %FALSE, you can set #GtkRange:round-digits instead.
Note that rounding to a small number of digits can interfere with
the smooth autoscrolling that is built into #GtkScale. As an alternative,
you can use the #GtkScale::format-value signal to format the displayed
value yourself.
