A simple algorithm (in Pseudo Pascal) would be:

        if NumberToConvert < 0 then
                result := '-0'
        else
                result := '0'; {result is a string}
                                        {digit is a character}
        while NumberToConvert <> 0 do
                begin
                        digit := NumberToConvert mod 10;
                        result := result + digit;
                        NumberToConvert := NumberToConvert div 10;
                end;

Havn't tested this code; quite sure this will work; learned it from
an algebra book that I read in '57 or '58.

If Ziggy says "Time is what keeps everything from happening at once",
and Newton teaches that Gravity brings all matter together, could we
say that Time and Gravity have an antagonistic relationship?
