Round a double to 2 significant figures after decimal point

I know that there are plenty of examples on how to round this kind numbers. But could someone show me how to round double, to get value that I can display as a String and ALWAYS have 2 decimal places?

Answer 1

One easy way to do it:

    Double d;
    Int i;
    D+=0.005;
    i=d*100;
    Double b = i/100;
    String s = b.toString():

Answer 2

You can use String.format("%.2f", d), your double will be rounded automatically.
