# **APA** : C++ big integers and dynamic precision floating points.
https://mrdcvlsc.github.io/APA
[](https://opensource.org/licenses/MIT)
A C++ library for big integers and dynamic precision floating points (big numbers),
pure c/c++ implementation, no handwritten inline-assembly.
**Version 0.4.8 Status : [WIP - Work In Progress]**
This branch (**version 0.4.8**) is an ongoing rewrite of the whole library.
**Visit branch [version 0.3.9](https://github.com/mrdcvlsc/APA/tree/version_3.9)
for the latest previous working version.**

### **Links**
- [**Documentation**](docs/docs.md) - learn how to use the library.
- [**Quick-Tutorial**](docs/quick-tutorial.md) - learn how this library works internally.
- [**Performance Comparison**](benchmark/comparison.md) - performance was compared with
other light-weight popular C++ big integer libraries.
-----
### **Environment Requirements**
| | |
| ---------------- | ---------------- |
| **Byte Order** | little-endian |
| **OS** | Windows, Linux |
| **Architecture** | x86, x64, x86-64 |
| **Compilers** | clang, GCC |
If your system does not have these requirements, it **might** produce wrong
results (on other system this could still work, but the chances of the tests
failing will be higher).
-----
### **Description**
This is a C++ **A**rbitrary **P**recision **A**rithmetic library. Used to compute
big integers and real numbers/floating point numbers. If you need to compute numbers that
is greater than the max value of `long long int`, `int64_t` or
`__int128_t` this library can do it for you.
-----
### **About**
This repository started as a personal hobby project **not intended** to
replace big number libraries like [boost multiprecision](https://www.boost.org/)
and [gmplib](https://gmplib.org/) and is **only for didactic purposes**.
Though performance is still a priority, meaning this library will... as much
as possible, use the fastest and the most efficient algorithms and
implementations THAT THE AUTHOR(s) KNOW OF.
