java round double to 2 decimals
double roundOff = Math.round(a * 100.0) / 100.0;
// Or
double roundOff = (double) Math.round(a * 100) / 100;
// both have the same output.java round double to 2 decimals
double roundOff = Math.round(a * 100.0) / 100.0;
// Or
double roundOff = (double) Math.round(a * 100) / 100;
// both have the same output.java double 2 decimal
