# Usage
|
|
|
|
|
Create objects of the BigInt class, and do what you got to do!
|
|
|
|
|
|
|
|
|
|
``` cpp
|
|
|
|
|
#include <bigint.h>
|
|
|
|
|
|
|
|
|
|
BigInt big1 = 1234567890, big2;
|
|
|
|
|
big2 = "9876543210123456789098765432101234567890";
|
|
|
|
|
|
|
|
|
|
std::cout << (big1 * big2 * 123456).getSring() << "\n";
|
|
|
|
|
// Output: 1505331490682966620443288524512589666204282352096057600
