How To Install fast_float-devel on CentOS 8
Introduction
In this tutorial we learn how to install fast_float-devel on CentOS 8.
What is fast_float-devel
The fast_float library provides fast header-only implementations for the C++ from_chars functions for float and double types. These functions convert ASCII strings representing decimal values (e.g., 1.3e10) into binary types. We provide exact rounding (including round to even). In our experience, these fast_float functions many times faster than comparable number-parsing functions from existing C++ standard libraries.
We can use yum or dnf to install fast_float-devel on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install fast_float-devel.
Install fast_float-devel on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
