-By default, the input numbers are rounded. To allow for more decimal places,
-use this option.
+This specifies how many decimals will be allowed until the field rounds
+the submitted value (via ``rounding_mode``). For example, if ``scale`` is set
+to ``2``, a submitted value of ``20.123`` will be rounded to, for example,
+``20.12`` (depending on your `rounding_mode`_).
