Sets the number of decimal places to which the value is rounded when it is
changed. This also sets the number of digits shown in the displayed value
when using the default handler for the #GtkScale::format-value signal.
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.
