This project is part of the csBigInteger macro project, a C# BigInteger implementation on Python
There are two different basis for this project: one native dotnet/python and another that uses csBigInteger.cpp portable C++ project: https://github.com/neoresearch/csBigInteger.cpp
Note that portable C++ itself has two implementations, csbiginteger_gmp.so and csbiginteger_mono.so. The GMP is straightforward, since it only depends on GNU GMP runtimes, and Mono implementation depends on mono runtime and csbiginteger_dotnet.dll.
First, you need to have csbiginteger_gmp.so (or csbiginteger_mono.so) shared library (just type make vendor).
This command will also install debian/ubuntu dependency on GNU GMP library (from csBigInteger.cpp project): sudo apt install libgmp-dev.
Don't worry, we are already shipping a linux x86-64 library for you (no default windows build yet.. help is appreciated!). Current default is csbiginteger_mono.so, so you will need csbiginteger_dotnet.dll on your path (also shipped for you).
Important: Remember to clone csBigIntegerpp portable submodule (git clone --recursive or git pull --recurse-submodules).
If you want to use ported native version, you need to install few extra dotnet dependencies.
python3.7 -m pip install pip
pip install msl-loadlib --user
pip install pycparser --user
pip install pythonnet --user
These may require mono to be installed.
Deepin uses Ubuntu 16.04 deps:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
sudo apt install apt-transport-https ca-certificates

sudo apt update
sudo apt install mono-complete
cd csbiginteger/dotnet
dotnet build -c Release (this should generate csbiginteger.dll inside dotnet/bin/ folder)
To publish:
dotnet publish --configuration Release --self-contained (see publish folder on bin)
Try python3 test_cpp.py code, it should work! (or just type make run):
from csbiginteger.BigInteger import BigInteger # or, use dotnet version from csbiginteger.BigIntegerNet import BigIntegerNet def main(): big = BigInteger() print('length = ', len(big)) print('to_int = ', big.to_int()) print('to_str: ', big.to_str()) print('') bigM1 = BigInteger(-1) print('length = ', len(bigM1)) print('to_int = ', bigM1.to_int()) print('to_str: ', bigM1.to_str()) print('') big4293967296 = BigInteger(4293967296) print('length = ', len(big4293967296)) print('to_int = ', big4293967296.to_int()) print('to_long = ', big4293967296.to_long()) print('to_str: ', big4293967296.to_str()) print('') bigff = BigInteger(b'\xff') print('length = ', len(bigff)) print('to_int = ', bigff.to_int()) print('to_long = ', bigff.to_long()) print('to_str: ', bigff.to_str()) print('') big100 = BigInteger('100') # base 10 implicit print('length = ', len(big100)) print('to_int = ', big100.to_int()) print('to_long = ', big100.to_long()) print('to_str: ', big100.to_str()) print('') big0001 = BigInteger('0x0001', 16) # big-endian input string print('length = ', len(big0001)) print('to_int = ', big0001.to_int()) print('to_long = ', big0001.to_long()) print('to_str: ', big0001.to_str()) print('') big101 = big100.add(big0001) # big100 + big0001 print('length = ', len(big101)) print('to_int = ', big101.to_int()) print('to_long = ', big101.to_long()) print('to_str: ', big101.to_str()) print('') big99 = big100.sub(big0001) # big100 - big0001 print('length = ', len(big99)) print('to_int = ', big99.to_int()) print('to_long = ', big99.to_long()) print('to_str: ', big99.to_str()) return 0
Empty BigInteger is expected to be byte array 0x00, with size = 1 (byte) and int value zero.
