P1788 is a Ruby extension wrapping the C++ libieeep1788 interval arithmetic library.
The goal of this gem is to allow doing basic arithmetic in Ruby on set-based intervals. The output of operations are guaranteed to enclose the true result of operations.
Forward-mode and reverse-mode elementary functions are implemented to allow building contractors.
The API documentation is hosted on rubydoc.info.
You can also build the documentation yourself from the sources:
# Install yard if you don't have it
gem install yard
# Clone the repository on your machine
git clone https://gitlab.ensta-bretagne.fr/bollenth/p1788.git
cd p1788
# Build the documentation
yard
# Open it!
firefox doc/index.html
Basically:
gem install p1788
To compile, P1788 requires to have the GNU GMP and MPFR development libraries installed on your machine, as well as the Ruby development headers:
sudo apt install libgmp-dev libmpfr-dev ruby-dev
A copy of libieeep1788 is embedded into this gem, so you do not need to install it.
However, if an installation of libieeep1788 is found on your machine while the gem is installing, it will be used instead of the embedded copy.
