Please advise how to make correct percentage view with only 2 digits after comma.
now I have:
System.out.println("    Margin use = " + (u / c * 100) + "%")
.............
output

 Margin use = 1.5060808012349864%

so if you have it like that:

    double amount = (u / c * 100);
    NumberFormat formatter = new DecimalFormat("#0.00");
System.out.println  ("Margin Use = " + formatter.format(amount) + "%")
