    In order to use very huge floating point numbers or floating point numbers with a large number of digits after the comma you need to design your own datastructure and operations that will work on it.

    If you do a search on this board, you will find some other threads about this.

    There are many ways to do this. One way is to use linked lists, where each node contains a digit.

    Code:
    typedef struct _digit_s digit_s;
    struct _digit_s
    {
        char digit;
        digit_s *next_digit;
    };
    You could define a special character to represent the comma.

    Code:
    #define COMMA -1
    Then you could do things just the same way you would do it on paper. Take care of the comma-position and the carry.

    A different approach is using strings to store a number.

    Download a package called NTL and link in into your program. It has a class for large float operations with arbitrary precision.

    Second time I have recommended this in ten minutes.
