Issue in Deleting Last Digit: Unexpected 0.90 Instead of 1 in Number Reduction Function I created a function that allows numbers to be added sequentially on a keypad in increments of *10. The logic works as follows:Press 1 → Adds 1 Press 2 → Updates to 12 (appending 2 after 1) Press 3 → Updates to 123Similarly, I implemented another condition where pressing 1 three times should result in 111 instead of 12 or 123. I’ve attached a screenshot named 'add' to show this functionality.Issue with Number DeletionNow, I’m working on the minus function, which should remove digits in reverse order:For 123, the deletion should happen like this: 123 → 12 → 1 → 0 For 111, it should go: 111 → 11 → 1 → 0I’ve attached a screenshot named 'minus' for reference.The ProblemWhen I test the function with 111, it works correctly—first becoming 11, then 1, and finally 0.However, when I test it with 123, it correctly removes 3, then 2, but when it should change 1 to 0, it unexpectedly changes it to 0.90 instead.What I Need Help WithWhy is this happening? Why does the last digit of 123 turn into 0.9
