APY calculation based on daily profit

[seb-qwerty]

Hi, I need some help with this calculation...
Say, I invested 100 $ today and today I was able to make a profit of 0.1 $. How would I calculate the APY % based on these numbers?

Feel free to delete my account, I didn't see the option to do that myself. The question has been answered on a different math forum
