We (the #MPFR team) are very proud to share the fact that GNU MPFR received a French open science award for free research software (Prix science ouverte du logiciel libre de la recherche). #GNUMPFR #freesoftware #logiciellibre #opensource

Does anyone know of a way to import a very high precision CSV file into R or another numerical language? I have some plain text data with floating points sometimes exceeding quad-precision decimal (34+ digits) which I'd like to work on using Rmpfr library, but import seems to be a stumbling block! #rstats #mpfr

Recently found out about libraries like #mpfr and gmp. Going to have some fun implementing an arbitrary precision #FFT algorithm to help quantify the numerical error. Here is the absolute error (bad metric I know) between FFTW and a #dft algorithm with 4 million points (69 hours of CPU time)

We have #glibc, #zlib, #binutils, #gmp, #mpfr and #mpc ... in theory everything needed to build a full-featured native #gcc for C and C++. Oh wow. Now, trying to create *this* port 😎

Edit: My hope is that with the --sysroot option (set to ${LINUXBASE}), this new toolchain will only ever look for libraries inside ${LINUXBASE}, avoiding weird build issues you might get when using the existing linux-c7-devtools port. Well, I'm not sure I fully understand this --sysroot magic 🙈

Updated my build instructions for #GMP / #MPFR / #MPC using #Emscripten, prompted by github stalebot commenting on an issue I had a year ago.

Seems 64bit works now (no need for 32bit chroot, and anyway it seems Emscripten no longer supports 32bit afaict?) so that simplifies things.

It got faster too, now the JS in Node runs only 15x slower than native, rather than 90x slower than native.

Compiling GMP/MPFR with Emscripten

Alright, this has been driving me insane. I've been trying this for at least a month, and no where on the internet is helping. I followed the steps of this. Not even the example works when I do th...

rounded is a Haskell package for correctly-rounded arbitrary-precision floating-point arithmetic, binding to the MPFR C library. I took over the maintainership last year.

The next releases will be twofold, with branches for MPFR 3.1 (rounded-0.x) and MPFR 4.0 (rounded-1.x). Users should depend on the lowest version(s) that have all the features and bug-fixes they need.

Changes since the previous release are a bug-fix for an embarrassing crash in the long double support, and wrappers for more of the MPFR API.

You can check the release candidates at:
https://hackage.haskell.org/package/rounded-0.2/candidate
https://hackage.haskell.org/package/rounded-1.0/candidate

I use rounded in et, an escape time fractal explorer, as well as other projects. The image was made with et.
