C++ round double values to a precision of 3 decimal places
By tahsynx, history, 9 years ago, In English

printf("%.3lf\n", -0.0001); This shows -0.000, but shouldn't it be 0.000?

How to print it correctly ? Without the minus sign, only 0.000 ?

No, it shouldn't be 0.000, because there's notion of signed zero in the doubles standard.
