Problem / Steps to reproduce

The output of my_number column is the following:

┌────┬────────┬─────────────┬──────────┐
│ Id │  Sex   │ my_number   │ Embarked │
├────┼────────┼─────────────┼──────────┤
│ 1  │ male   │ 12345.54321 │ S        │
│ 2  │ female │ 123.321     │ C        │
│ 3  │ female │ 123         │ S        │
│ 4  │ female │ 12.21       │ S        │
│ 5  │ male   │ 1.1         │ S        │
│ 6  │ male   │ 0.1         │ S        │

│ 8  │ male   │ 0.001       │ S        │
└────┴────────┴─────────────┴──────────┘

The output of my_number column in my mind is the following:

┌────┬────────┬─────────────┬──────────┐
│ Id │  Sex   │ my_number   │ Embarked │
├────┼────────┼─────────────┼──────────┤
