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.

String and ALWAYS have 2 decimal places?

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

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