docs: Defines the string to be used for the given number symbol.
  
  Calling this method with a null or undefined symbol removes a previously set symbol string.
  Note that an empty string is explicitly allowed.
  
  If a symbol is defined, it will be preferred over symbols derived from the current locale.
  
  See class {@link sap.ui.core.format.NumberFormat} for details about the symbols.
  
  After changing the number symbol, the framework tries to update localization
  specific parts of the UI. See the documentation of {@link sap.ui.core.Configuration#setLanguage}
  for details and restrictions.
  
  @param {string} sStyle must be one of decimal, group, plusSign, minusSign.
  @param {string} sSymbol will be used to represent the given symbol type
  @return {sap.ui.core.Configuration.FormatSettings} Returns <code>this</code> to allow method chaining
