Converting string to double with dot

Question

I need to convert string value to double with dot. Here is simple code

double dValue=Double.parseDouble("999999999.99");
System.out.println(dValue);
output is: 9.9999999999E8

When i gave value like 10000 or 100000 it works. Help me to overcome this problem.

`999999999.99` is equivalent to `9.9999999999E8`. – niyasc Apr 07 '16 at 11:08 — niyasc, Apr 07 '16 at 11:08

You can use String.format

System.out.println(String.format("%.2f", dValue));

You could use BigDecimal and toPlainString() for that.

BigDecimal dValue= new BigDecimal("999999999.99");  
System.out.println(dValue.toPlainString());

Output:

999999999.99

Thank you islam. Also i need to divide this value by 2. How to achieve this. And the precision value should be round. Could you help me – Apr 07 '16 at 11:38
@MuthuVikki see for division ``dValue.divide(new BigDecimal(2));`` – muzahidbechara Apr 07 '16 at 11:47
@MuthuVikki for precision ``new BigDecimal("23.45435436").setScale(3, BigDecimal.ROUND_HALF_UP)`` – muzahidbechara Apr 07 '16 at 11:54
