Lets say I want to print a table with floats. How can it be formatted like that:
|  2.4   |
| 12.2   |
|  8.131 |
| 17.44  |
Also acceptable is
|  2.400 |
| 12.200 |
|  8.131 |
| 17.440 |
but not
| 02.4   |
| 12.2   |
| 08.131 |
| 17.44  |
or any other solutions with leading zeros.

Use %#6.3f to get the above output.

I have this one:

----
import std.stdio;
import std.string, std.algorithm, std.format;

void main(string[] args)
{
    [2.4, 12.2, 8.131, 17.44].each!(a => format("%.3f", a)
        .rightJustify(6).center(8).center(10,'|').writeln);
}
----

But only works if fractional and integral part are both up to 3 digits.

Also try "%.3g".
