Description
R MPFR - Multiple Precision Floating-Point Reliable.
Description
Arithmetic (via S4 classes and methods) for arbitrary precision floating point numbers, including transcendental ("special") functions. To this end, the package interfaces to the 'LGPL' licensed 'MPFR' (Multiple Precision Floating-Point Reliable) Library which itself is based on the 'GMP' (GNU Multiple Precision) Library.

Installation and Reference of the R package 'Rmpfr'
Installation is non-trivial if you install from _source because of the SystemRequirements (listed in ./DESCRIPTION):
The package Rmpfr interfaces R to the C Library MPFR:
MPFR, the "Multiple Precision Floating-Point Reliably" library
which is Free/Libre Software, available under the LGPL license. MPFR Website
MPFR itself is built on and requires the GMP library
GNU Multiple Precision arithmetic library (GMP)
Obtain that from GMP Website or from your operating system vendor / package system:
+ Under _Debian_, _Ubuntu_ (and other Debian derivative) Linux distributions,
it is sufficient (for *both* libraries) to simply do
sudo apt-get install libmpfr-dev
+ In Fedora, Redhat, CentOS, opensuse, etc, you get these via
sudo dnf install mpfr-devel
The standard reference to MPFR is
