Introduction

In this tutorial we learn how to install mpfr on Fedora 34.

What is mpfr

The MPFR library is a C library for multiple-precision floating-point computations with “correct rounding”. The MPFR is efficient and also has a well-defined semantics. It copies the good ideas from the ANSI/IEEE-754 standard for double-precision floating-point arithmetic (53-bit mantissa). MPFR is based on the GMP multiple-precision library. mpfr 4.1.0 7.fc34 i686 355 k mpfr-4.1.0-7.fc34.src.rpm updates C library for multiple-precision floating-point computations https LGPLv3+ The MPFR library is a C library for multiple-precision floating-point computations with “correct rounding”.

Metadata cache created.

After updating yum database, We can install mpfr using dnf by running the following command:

sudo dnf -y install mpfr

Install mpfr on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
