precision and rounding and maybe other settings for float type needs to be adjusted

is enum what I should use?

I checked c++ in a nutshell by oreilly, but I can't seem to find any thing from it about enum.


how do I do this?

you need to learn about STL output manipulators:

cout.precision(0);
cout <<   fixed    << a  << endl;

There are lots of manipulators, have a look to:

are you saying that it's cout that chop off the parts, not the float type itself?

float value remains untouched. It is just a presentation matter.
