Factorial 100!
How can i find factorial of 100! ?

the factorial of 100 or the factorial of 100!?
according to my calculator, the factorial of 100 is 9.33x10^157, which requires an unsigned integer of 525 bits (66 bytes) to hold it
my calculator claims that the factorial of 100! is infinity

There is no way you're going to fit that number into a standard data type. You could use a large array of bytes and treat it as a "big integer".
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
Though ... post #2 gave you the answer so you don't need to do it anymore. It's 9.33x10^157.
- use your head to think about the problem in detail, rather than just writing the obvious for loop to do all the work
- use a bignum library like this -> The GNU MP Bignum Library
- write your own bignum functions sufficient to solve the problem.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
The factorial of even 1 billion is larger than most computer's memories.Originally Posted by ಠ_ಠ
