    i think that is correct output..

    if you can see you put this "%5.2f" which is equivalent into FLOAT..that has 2decimal places
    in C/C++
    if you write that
    it means you have a value to transfer
    like this

    System.out.printf(" input float(e.g. %5.2f): ", 2.43);

    you transfer the value of 2.43 into float..
    thats why the output is

    input float(e.g. 2.43):


    hmm i think that is the explanation.. hmmm..
    you use SYSO thats why they print the output.
    input float(e.g. 2.43):

    like PRINTF /COUT
    -------------------------------
    System.out.printf(" input float(e.g. %5.2f): ", 2.43);
    input float(e.g. 2.43):
