title: How to convert base 10 to base 16 using while loop?
body: <p>Currently, my program works fine for the bases I tested such as 1-9, but when I try to convert base 10 to base 13 or base 16, it give me a number rather than the ASCII letter value.
  For example, 
  250 base 10 to base 16 returns: 160
  When it should return "FA"</p>
