Limiting decimals on a float output

-----------------------------------

Okay so basicaly I want the result of calculation to come out with max 2 decimals

System.out.printf("%.2f",23.556849);
or look up Math.round , but printf is better

well Math.round will... round. printf is used for formatting. The latter is probably a better approach in this case.
