QtBigInt - Arbitrary-sized integer class for C++ and build system of Qt (qmake)

Features

• No additional dependencies other than the standard library.
• Support for all arithmetic operators, which allows you to easily integrate the library into any of your algorithms.
• Based on the minigmp 6.1.2 library that provides high performance.

Build

• git clone https://github.com/QuasarApp/QtBigInt.git
• cd QtBigInt
• qmake -r
• make -j8
• make test #(for testing)

Include

for qmake projects

• cd yourRepo
• git submodule add https://github.com/QuasarApp/QtBigInt.git # add the repository of Qt-Secret into your repo like submodule
• git submodule update --init --update
• Include in your pro file the pri file of Qt-Secret library

include($$PWD/QtBigInt/GMP.pri)

• Rebuild yuor project

for other build system

• cd yourRepo
• git submodule add https://github.com/QuasarApp/QtBigInt.git # add the repository of Qt-Secret into your repo like submodule
• git submodule update --init --update
• Add the rule for build Qt-Secret
• Add INCLUDEPATH and LIBS for your build system
• Rebuild yuor project

Usage

Create objects of the BigInt class, and do what you got to do!

#include <bigint.h>

BigInt big1 = 1234567890, big2;
big2 = "9876543210123456789098765432101234567890";

std::cout << (big1 * big2 * 123456).getSring() << "\n";
// Output: 1505331490682966620443288524512589666204282352096057600
