How to convert java double into 2 decimal value

Question

Question 1:

Assume Double d = 10.233444. I want to convert and put result into same double, so that my value should be d= 10.23;

Question 2:

Assume Double d = 10.235444. I want to convert and put result into same double, so that my value should be d= 10.24;

How to do this in java?

That is not even rounding up the values. It is to get the fractional part's first three values and then rounding them up. — Afzaal Ahmad Zeeshan, Aug 26 '14 at 19:42

If you want to roundoff value

Double d = 10.233444;

double roundOff = Math.round(d * 100.0) / 100.0;
System.out.println(roundOff);
// Output is 10.24

Double d2 = 10.235444;

roundOff = Math.round(d2 * 100.0) / 100.0;
System.out.println(roundOff);
// Output is 10.25

Why multiply by 100 then divide by 100? – Afzaal Ahmad Zeeshan Aug 26 '14 at 19:47
