  • So you want to convert a persian text to an decimal output. Search some library or do it youself, I dont believe java has a default library to do that. – kunpapa Feb 03 '16 at 11:19

You could breakdown the String into chars and iterate through the characters using, for example, toCharArray() and then convert each number to its English equivalent.

String number = "";
for (char c : txtProductSalePrice.toCharArray()) {
    if (c == "۱") {
        number.concat("1");
        continue;
    }
    if (c == "۲") {
        number.concat("2");
        continue;
    }
    ....
}
return new BigDecimal(number).doubleValue();

I'm sure this could probably be improved though, and I'm not entirely sure whether char will support non-Roman letters.

If you use Calligraphy it's solve your problem. apply your precision-things to your text and this library do rest of things for you.

PS : you should use proper Farsi font
