Re: Code for converting between Elisp and Calc floats

[Richard Stallman]

That code needs a lot more comments to explain what's happening.
Also, would you please format the code in accord with the Emacs coding
style?

  /* voir (elisp) Writing Emacs Primitives*/
  if(NILP(is_special))
        {
          double_map_ot double_map_o;
          int exp_val = XINT(exp);

should be

  /* voir (elisp) Writing Emacs Primitives*/
  if (NILP (is_special))
    {
      double_map_ot double_map_o;
      int exp_val = XINT(exp);


And why does it say "voir"?  Is that French?  Is it a typo for `void'? 
If it is a typo for `void', I don't understand the meaning.
