Hi Krzysztof,
 You can do it with a couple of lines of code in C/C++:
 ----------------------------------------------------------
  char string_after_conversion[10000]; //make it big
  int int_to_convert;
  //read an int in int_to_convert
  sprintf(string_after_conversion, "%d", int_to_convert);
 ----------------------------------------------------------
  printf("%s\n",string_after_conversion); //verify...
 bye,
