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
@public
