    Variables longer than double or long int

    I've been trying to use C++ for running math equations. A recent problem i've found is the limit for size on variables.
    I am trying to find a way to solve for numbers, and use numbers in equations, that are much longer than even long int.
    I'm trying to use numbers that are tens of digits long and still retain accuracy. After doing some searching on it,
    I still haven't found any way to accomplish this in C++. If anyone could help, or knew any books that would have an answer,
    I'd appreciate it greatly. Thanks for your time.

    You can check out GMP, which is a C/C++ library for large number operations.
