** The following two functions together make up an itoa()
** implementation. Function i2a() is a 'private' function
** called by the public itoa() function.
**
** itoa() takes three arguments:
** 1) the integer to be converted,
** 2) a pointer to a character conversion buffer,
** 3) the radix for the conversion
** which can range between 2 and 36 inclusive
** range errors on the radix default it to base10
** Code from http://groups.google.com/group/comp.lang.c/msg/66552ef8b04fe1ab?pli=1
