How To Install qd on Fedora 34

qd is Double-Double and Quad-Double Arithmetic Double-Double and Quad-Double Arithmetic

Introduction

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

What is `qd`

This package provides numeric types of twice the precision of IEEE double (106 mantissa bits, or approximately 32 decimal digits) and four times the precision of IEEE double (212 mantissa bits, or approximately 64 decimal digits). Due to features such as operator and function overloading, these facilities can be utilized with only minor modifications to conventional C++ and Fortran-90 programs. In addition to the basic arithmetic operations (add, subtract, multiply, divide, square root), common transcendental functions such as the exponential, logarithm, trigonometric and hyperbolic functions are also included. qd 2.3.22 4.fc34 x86_64 159 k qd-2.3.22-4.fc34.src.rpm fedora Double-Double and Quad-Double Arithmetic https LBNL BSD This package provides numeric types of twice the precision of IEEE double (106 mantissa bits, or approximately 32 decimal digits) and four times the precision of IEEE double (212 mantissa bits, or approximately 64 decimal digits).

We can use yum or dnf to install qd on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install qd.

Install qd on Fedora 34 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

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

sudo dnf -y install qd

Install qd 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

Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

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

sudo yum -y install qd

How To Uninstall qd on Fedora 34
