Minimum amount for wallet transaction not respected

I wanted to send 0.1 AVAX to an external wallet using the API. When I tried the code I received an error saying that I have to send a minimum amount of 0.100 AVAX, which I was. And I also had the amount available.
The transaction worked well when I tried with 0.2 AVAX.

So my question is: When you mention a minimum amount to send, do you mean “OVER 0.1” or " OVER OR EQUAL TO 0.1"?
