How to find the middle value of an integer without converting it to a string using Python3?
Question: While solving the next [smallest palindrome
problem](https://github.com/harishvc/challenges/blob/master/string-next-
palindrome.py), I had to convert an integer to a string so I can reverse and
find the middle value. There has to be a solution - how to find the middle
value of an integer without converting it to a string using Python3?
Appreciate your assistance. Thanks.

Examples:

  1. input=78653, result=6
  2. input=7564, result=5 


Answer: This is a start.  
It needs some tweaking:  

    
    
    import math
    
    def mid_digit(n):
    
        # num of digits
        a = math.trunc(math.log(n,10)+1)    
    
        # moving half of digits to the right of decimal point
        b = n / 10 ** round(a/2 + 0.5)
    
        # getting the left most decimal digit
        c = math.trunc(math.modf(b)[0] * 10) 
    
        return c
