As in this question is said, there is some differences between negative and positive zero in floating point numbers. I know it's because of some important reasons. what I want to know is a short code to avoid negative zero in output.
for example in the following code:
cout << fixed << setprecision(3);
cout << (-0.0001) << endl;
"-0.000" is printed. but I want "0.000".
Note all other negative numbers (e.g. -0.001) should still be printed with the minus sign preceding them, so simply * -1
will not work.
