doublereadThisDouble(final String value)
read This Double 
double res;
final String trimmed = value.trim();
if (trimmed.toUpperCase().equals("NAN"))

StringrenderDouble(double value, int precision)
render Double 
return renderDouble(value, precision, ',');
StringreplaceCommaByPoint(String doubleString, Locale loc)
If a decimal number contains a comma and no point, and if the given locale uses a comma for decimal separator, the comma is replaced by a point. 
DecimalFormatSymbols symb = new DecimalFormatSymbols(loc);
if (symb.getDecimalSeparator() == ',') {
    if (doubleString.indexOf(',') >= 0 && doubleString.indexOf(',') == doubleString.lastIndexOf(',')
            && doubleString.indexOf('.') == -1) {
        return doubleString.replace(',', '.');
return doubleString;
...
StringsanitizeDouble(String value)
Normalizes the decimal separator for the user's locale. 
value = value.replaceAll("[^0-9,\\.]", "");
final char separator = new DecimalFormatSymbols().getDecimalSeparator();
final char usedSeparator = separator == '.' ? ',' : '.';
value = value.replace(usedSeparator, separator);
try {
    Double.parseDouble(value);
} catch (final Exception e) {
    value = value.replace(separator, usedSeparator);
