docs: Returns a copy of this style with the specified absolute value setting.
  <p>
  If this is set to true, the absolute (unsigned) value will be output.
  If this is set to false, the signed value will be output.
  Note that when parsing, signs are accepted.
  
  @param absValue  true to output the absolute value, false for the signed value
  @return the new instance for chaining, never null
