Is there a function that rounds to two decimal places?

Question

I have to write a program and in the program I have to round to two decimals (quote: "The output value of A should be exactly two decimal places."). So is there a function in C++ that does this and what is it?

Answer 1

Give a look in fixed and setprecision().
