When compiling the next program under cfron ports 2.0 and 2.1 the output
in both cases is not what I expect it to be:
#include <iostream.h>
main()
{
cout.setf(ios::showpoint);
cout.precision(3);
cout << 0.1 << endl << 1.1 << endl;
}
Output:
0.100
1.10
The extra 0 from 0.1 is a little too much :-(
Is this a known bug, or am I wrong? In both cases, is there a fix?
Thanks.
Leo

In both cases, is there a fix? Since a while I think it is not a bug, I didn't understand ios::precision(). What I want is this: given some floats I want them to be inserted in a stream in a columnwise fashion (like printf "%8.3f") i.e.: .... some statements setting the format cout <<setw(8) << 123.45 << " " <<setw(8) << 121.1 << endl; cout <<setw(8) << 23.45 << " " <<setw(8) << 21.1 << endl; cout <<setw(8) << 0.1 << " " <<setw(8) << 1.0 << endl; giving: 123.450 121.100 23.450 21.100 0.100 1.000 Is this possible with ios formatting capabilities?
