Summary: setprecision rounding fails in some cases
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: libstdc++
AssignedTo: unassig...@gcc.gnu.org

cecilio@pp1:~$ gcc --version
gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3
I'm having problems with truncation. For instance, following code:
cout << "test precision 5798.12500: "
<< fixed << setprecision(2) << setfill(' ')
<< setw(10) << 5798.12500 << endl;
cout << "test precision 5798.87500: "
<< fixed << setprecision(2) << setfill(' ')
<< setw(10) << 5798.87500 << endl;
Generates inconsistent results: 5798.12 (wrong, should be 5798.13) and 5798.88
(right).
In first case rounds up and in second, down.
The same code, compiled with Microsft Visual Studio, produces the right results
in the same machine.
