Large Datatype

[Joshi Abhishek]

Does a datatype exist in C++ which can store the value of 100^100 ??

I find it a big limitation in C++..the inability to store large values by variables !!!

Your Suggestions will be duly respected and entertained.

Use an arbitrary precision library, like GMP. It should handle "unlimited" large values, assuming you have enough memory.

Try linux :D

There are 2 commands in most linux shells that can do large arithemetic like that. bc and dc

$ echo '100^100' | bc | tr -d '\\ '
10000000000000000000000000000000000000000000000000000000000000000000
00000000000000000000000000000000000000000000000000000000000000000000

$ echo '100 100 ^ p' | dc | tr -d '\\ '
100000000000000000000000000000000000000000000000000000000000000000000
