I recently read that this formula,
(Number / 10^K-1) % 10
Edit: updated formula to use K-1
Will give me the Kth digit of Number.
For example if i want the 2nd digit from 345, I have (345/100)%10 which gives 4.
Why does this work? 🤔
In: 3
Pretty sure it’s (Number / 10^K-1 ) % 10
In your example 345/100 = 3.45, and 3.45 % 10 = 3.45 (if you’re working with whole numbers when dividing it’s 3 in both cases.)
