将字符串号格式化为双精度变量，小数点后有两个数字

Question

I'm getting from server a string value formatted as follow: 14.5000 I need to create a double variable from it with two number after decimal point: 14.50 . I've tried the following:

     DecimalFormat df = new DecimalFormat("#,00");
     Double priceD = Double.parseDouble((produitParam.item(paramNb).getTextContent()));
     String dx = df.format(priceD);
     produit.setPrixTtc(Double.valueOf(dx));

And I'm getting 14.5 . If I use DecimalFormat("#.00") , it gives me 15 ...

Someone could help me with that ?

Answer 1

If you want string with precision upto 2 points after decimal you should use

DecimalFormat df = new DecimalFormat("#.00");

you have used "#,00"

',' is used for specifying grouping Separator.
