This repository was created to collect the best portable fast math functions on the internet. Because its goal is to provide portable approximations, you won't find SIMD-based algorithms here.
Currently most of the code here comes from pt_math. Another important source is the hacker's delight website.
You can easily make a testing executable which will generate svg
graphics with charter and write some basic benchmarking logs.
A copy of the resulting files can be found in the res folder,
but if you choose to re-generate them they will be written in bin.
The makefile includes the following targets
- bin/mpiric (phony): makes the testing executable
- bin/charter_svg: makes the charter svg graph generator
- run: runs the executable to generate svg graphs and write benchmarking logs
- svg: copies the svg files in the res folder
Github seems to break svg files rendering, please open them independently in your browser by right-clicking on them and choosing "view image".
To clone this repository use the following command
make github
Everything here is public domain work, except of course
the charter submodule used to generate graphs.
