When you have an answer like :

  2.149999

what do you print?

  2.15 or
  2.14 ?

i mean do you round or cut ?

and by the way, what can i use in C++ for printing
only 2 digits after the point. cout.precision i not
working for 14.10 for example.

I use c,and need not worry about rount or cut,just use
'printf("%.2lf",result);' is enough.

This one really works in C but here, it gets
'Compilation error' with C++! However , on my BC++ 3.1
compiler
it works..
