12 | What the Big Integer Library provides |
| 13 | ===================================== | |
| 14 | This library contains two classes, BigUnsigned and BigInteger, that represent nonnegative integers and integers, respectively, of size limited only by your computer's memory. Their capabilities include these operators: | |
| 15 | Math: + - * / % & | ^ unary- | |
| 16 | Assignment: = += -= *= /= %= &= |= ^= ++ -- | |
| 17 | Comparison: == != < <= > >= | |
| 18 | In the works are the << and >> operators, integer algorithms like `gcd', and possibly a working implementation of RSA using the library. | |

20 | Using the features of the library |
| 21 | ================================= | |
| 22 | The file `sample.cc' explains and demonstrates the most important features of the library. I recommend that you read `sample.cc' and then run the sample program it contains. If you want to do something not shown in `sample.cc' or want more detail, read the actual header and source files, which are extensively commented. | |

24 | Compiling programs with the library |
| 25 | =================================== | |
| 26 | The library consists of a folder full of header files (`.hh') and source files (`.cc'). `#include' header files and compile with source files as necessary for your own programs. For those who use `make', a `Makefile' is included that compiles the source code to object files (`.o') and compiles the sample program. | |

28 | Bugs |
| 29 | ==== | |
| 30 | The library has been tested by myself and others but is by no means bug-free. The programs you write using the library will be the best test of its correctness. I urge you to report any problems that you find, whether they come in the form of compiling trouble, mathematically inaccurate results, or runtime memory-management bloopers (which, since I use Java, are altogether too common in my C++). | |

32 | Keep in touch |
| 33 | ============= | |
| 26a5f52b | 34 | Feel free to e-mail me at `hashproduct@gmail.com' to report bugs or request features. When I fix the bug or add the feature, you will generally be credited by name in the source code and/or the Change Log unless you request otherwise. I am also curious as to what uses you find for the library. New versions of the library will be available at the project Web site. |
