I have a little problem:
in a method I have

cout.setf(ios::showpoint);
cout.precision(2);
cout<<number<<endl;

coutn<<number2<<endl; // this is the problem

this doesn't output number2 .

but if I take out precision(); it outputs just fine

what am I overlooking?

PLEASE help

Thanks

it is suppose to be.

cout.setprecision(2); //set two dec points
cout.setf(ios::fixed); //ENSURES it.
cout.setf(ios::showpoint);

in that order, other wise it is temporary.  :) I think, but the
above order is correct.  first how many, then permanent, the show the point.
hope that solves your problem.

The order should not matter.  (At least as far as I know.)

you say "this doesn't output number2 . "  Does that mean it doesn't ouput it all?  or do you mean it doesn't ouput it the way you want it.  If so, what do you get and what do you want?

I tried in the order that THE_BRAIN suggested and it worked fine
