I am reading this massive book now Financial Instrument Pricing Using C++
1148 pages looong....stuffed with C++ code and tricks on derivatives, MC, PDE's and much more...well the last 6 pages are blank (good place to take own notes) so the book is actually only 1142 pages.
well the second edition seems like a massive extension of the first edition. First edition was only 432 pages or so...
Congratulations with the hard work!
(current amazon price 7.5 cents per page!)
