title: How to convert number to decimal string?
body: <p>Hi everyone (newbie here),</p>
  
  <p>I work on an embedded system and I need to convert hex number to an ASCII string.</p>
  
  <p>Please read before answering to understand what I am asking for.</p>
  
  <p>e.g. hexNumber = 0xFF
       ASCII = 0x32 0x35 0x35</p>
  
  <p>The ASCII bytes are representation of the decimal value of the hexNumber. I.e 0xFF is 255, 0xFE will be 254, etc...</p>
  
  <p>Essentially, each byte should generate 3 bytes for the decimal representation of the hex number.</p>
  
  <p>The value is not entered using the keyboard, it is a value obtained from a smart card.</p>
