docs: Sets the minimum number of digits allowed in the integer portion of a
  number.  This must be &lt;= maximumIntegerDigits.  If the
  new value for minimumIntegerDigits is more than the current value
  of maximumIntegerDigits, then maximumIntegerDigits will also be set to
  the new value.
  @param newValue the minimum number of integer digits to be shown; if
  less than zero, then zero is used. Subclasses might enforce an
  upper limit to this value appropriate to the numeric type being formatted.
