io - Java - Rounding off 2 decimal places -

lets have user input. class standing has total of 80 , exam 100. how round result off 2 decimal places?

system.out.print("grades = 50% class standing + 50% exams = " + (cs/160+exam/200)*100);

you can use printf():

system.out.printf(     "grades = 50%% class standing + 50%% exams = %.2f%n", (cs/160+exam/200)*100);

the %.2f specifier indicates float/double should rounded 2 decimal places. %n new line.

also note have escape literal %s % (i.e. %%) not mistaken format specifiers.

And
