Summary: The Real typedef should be used throughout

Initial Comment:
You have a typedef of real like so:

typedef double Real;

but throughout the code, you use ordinary doubles all 
over the place.  Hence, the typedef is basically useless.

If (on the other hand) throughout the code you used 
Real parameters and Real automatic variables, then I 
would be able to use the system with other data types 
such as Moshier's Qfloat, Scott's MIRACL, etc. by making 
my own typedef as follows:

typedef qfloat Real;

or similar to that.

We need to compute with 100 digits of accuracy, so a 
double simply won't do.

Hi,
    I have to admit that I even forgot about the Real typedef... 
We'll see what we can do. Does a textual replace of all 
"double" to "Real" work for you?

And just out of curiosity, 100 digits? What kind of financial 
application needs that accuracy?

Bye,
        Luigi
