--- Introduction ---
InfInt is simply a lightweight large integer library which consists of a header file. So, all you have to do is to include the header file provided and start using huge integers in your applications.
--- Details ---
It is pretty straight forward to use the library. Just create an instance of InfInt class and start using it:
InfInt myint1 = "15432154865413186646848435184100510168404641560358";
InfInt myint2 = 156341300544608LL;
myint1 *= --myint2 - 3;
std::cout << myint1 << std::endl;
Useful methods:
intSqrt: integer square root operation
log2: integer log2 operation
log10: integer log10 operation
digitAt: returns digit at index
numberOfDigits: returns number of digits
size: returns size in bytes
toString: converts it to a string
There are also conversion methods which allow conversion to primitive types:
toInt, toLong, toLongLong, toUnsignedInt, toUnsignedLong, toUnsignedLongLong.
You may define INFINT_USE_EXCEPTIONS and library methods will start raising InfIntException? in case of error instead of writing error messages using std::cerr.
