In the same spirit as setw( ) and setprecision( ), is there a stream
manipulator that will fill in closing-zeroes on those fractions with a given
setprecision( )?
For example, if setprecision(3) is used, I want '1' to be displayed as
"1.000", '1.2' to be displayed as "1.200", '1.23' to be displayed as
"1.230", '1.234' to be displayed as "1.234", and '1.2345' to be displayed as
"1.234" (or the rounded version "1.235" is ok too).
Thanx in advance!!!

std::fixed and std::ios_base::fixed are what you want. e.g.
#include <iostream>
#include <iomanip>
int main()
{
std::cout << std::setprecision(3) << std::fixed
<< 1.23456 << ' ' << 1.2 << '\n';
}
