--------------------
You are free to use this software according to the licensing terms specified at the end of this document.
If you use it for research purposes and produce publications, please cite the following paper 
that describes the underlying theory:

> M. Attene. Indirect Predicates for Geometric Constructions. In Elsevier Computer-Aided Design (2020).

-------------------
System Requirements
--------------------

The software has been tested on 64 bit PCs running:
 - Microsoft Windows OS with MSVC
 - Linux with standard gcc/g++ development environment
 - Mac OSX with both CLang and gcc

Usage
---------------------

The repository provides a header-only C++ library.
To use in your code:
1) Add the "$(DIRECTORY_CONTAINING_THIS_README)/include" path to the list of 
   paths where your compiler searches header files
2) Include "numerics.h" in your code 
3) Tell your compiler to use the compilation directives reported at
   the beginning of include/numerics.h

As an example, check the CMakeLists.txt provided to compile the test.cpp code.
