Another number fomatting question

Hello,

I was wondering if there is an easy way to align numbers with varying precision at the decimal point.

Examples:

111.1111
2.222222
-33333.3
44444444

....which should look like:

111.1111
2.222222
-33333.3
44444444

(I don't want to add trailing 0's, but rather leave the numbers as they are.)

Thanks in advance, Hermann
