String r1 = String.format("%f",d);        // 12345678.000000
String r2 = String.format("%10f",d);      // 12345678.000000
String r3 = String.format("%5.2f",d);     // 12345678.00
String r4 = String.format("%5.0f",d);     // 12345678

String r6 = String.format("%,5.0f",d);    // 12,345,678
String r7 = String.format("%d",d);        // throws an exception!
