Filter Only Decimal Numbers - Result In Same Column

I have few numbers in Column "A". Few are normal figures & few are decimal numbers, like this:

20
5
5.63
4.5
200
53.263
125.5

Now I want to filter only the decimal numbers, so that after filter the result will show like this:

5.63
4.5
53.263
125.5

But I don't want to use any other column for doing so. I can do it using MOD in other column but I want the result in the same column.
