I tried to solve a problem in C++, I tried to output the value which class is long double. When I used "%Lf" the output of my solution is -0.000000 on test #1 (it is a wrong answer) but according to my environment, the output is 1.333333 (it is a correct output). On Codeforces, can we use "%Lf" in C++? Or like "%lld", aren't we allowed to use it?
UPD: When I cast it to double, my solution worked.
