Clear low fractional shares

Hi. I have a few shares which have sub 0.0 fractionals on them due to pie buys which I no longer do.
How on earth do you tidy these up? You can’t sell or buy at that level even if adding a whole share into the mix.
I just want to get them to rounded numbers again.

Use pies. Suppose you have 5.00015. You want to trim off the annoying fractional bit. So import 4 to a pie. Sell what is left outside the pie. Rebuy 1 if you like and you will have 5. You lose a small bit on spread but it can be worth it to save your OCD cleanliness nerves.
