GWT get users local decimal separator char

How can I get users local decimal separator character from GWT. I have found the NumberFormat utility, which only returns the whole format and provides parsing.

NumberFormat.getDecimalFormat()...

Is there a (simple) way to get the decimal separator, thousand separator from the decimal format.

import com.google.gwt.i18n.client.LocaleInfo;

String decimalSeparator = LocaleInfo.getCurrentLocale().getNumberConstants().decimalSeparator();
String thousandSeparator = LocaleInfo.getCurrentLocale().getNumberConstants().groupingSeparator();

You can seed it with a known number and then parse it for the characters you want. 

import com.google.gwt.i18n.client.NumberFormat;

NumberFormat fmt = NumberFormat.getDecimalFormat();
double value = 1234.5;
String formatted = fmt.format(value);
String thousandSeparator = formatted.substring(1,2);
String decimalSeparator = formatted.substring(5,6);
