How To Install sleef on Rocky Linux 8
Introduction
In this tutorial we learn how to install sleef on Rocky Linux 8.
What is sleef
SLEEF stands for SIMD Library for Evaluating Elementary Functions. It implements vectorized versions of all C99 real floating point math functions. It can utilize SIMD instructions that are available on modern processors. SLEEF is designed to efficiently perform computation with SIMD instructions by reducing the use of conditional branches and scatter/gather memory access. The library contains implementations of all C99 real FP math functions in double precision and single precision. Different accuracy of the results can be chosen for a subset of the elementary functions; for this subset there are versions with up to 1 ULP error (which is the maximum error, not the average) and even faster versions with a few ULPs of error. For non-finite inputs and outputs, the functions return correct results as specified in the C99 standard.
