formula 1.0.0a6

Arbitrary-precision formula solver.

# formula
Python csformula wrapper.
==============

Development status: in developing

Thi project built with [pybind11](https://github.com/pybind/pybind11).

Installation
------------

**On Unix (Linux, OS X)**

- `pip install formula`

**On Windows (Requires Visual Studio 2015)**

- For Python 3.5+:
- clone this repository
- `pip install ./formula`
- For earlier versions of Python, including Python 2.7:

Pybind11 requires a C++11 compliant compiler (i.e. Visual Studio 2015 on
Windows). Running a regular `pip install` command will detect the version
of the compiler used to build Python and attempt to build the extension
with it. We must force the use of Visual Studio 2015.

- clone this repository
- `"%VS140COMNTOOLS%\..\..\VC\vcvarsall.bat" x64`
- `set DISTUTILS_USE_SDK=1`
- `set MSSdk=1`
- `pip install ./formula`

Note that this requires the user building `formula` to have registry edition
rights on the machine, to be able to run the `vcvarsall.bat` script.


Windows runtime requirements
----------------------------

On Windows, the Visual C++ 2015 redistributable packages are a runtime
requirement for this project. It can be found [here](https://www.microsoft.com/en-us/download/details.aspx?id=48145).

If you use the Anaconda python distribution, you may require the Visual Studio
runtime as a platform-dependent runtime requirement for you package:

```yaml
requirements:
build:
- python
- setuptools
- pybind11

run:
- python
- vs2015_runtime # [win]
```
