Download PARI/GP

If you intend to compile PARI/GP from a source distribution, make sure the GNU MP and GNU readline libraries are already installed on your system. They are not mandatory but make the gp calculator respectively faster and more user-friendly. (See the Extras section for details.)


You may also want to download some Optional Packages.

Source distributions

2.15.1 2022-11-02
Snapshot corresponding to the latest version with all current patches applied.

Windows, binary distributions

First determine whether you are running a 32-bit or 64-bit version of Windows (probably 64-bit on recent systems), then select the appropriate binary:
  • Stable 32-bit version: Pari32-2-15-1.exe (91.6 MB), Nov 2 2022
    md5sum: 1c02708c73700c1462fafd5a22bfd9ee
  • Stable 64-bit version: Pari64-2-15-1.exe (97.9 MB), Nov 2 2022
    md5sum: 816fa43d5069fd92728f229ed6ae3387
  • Daily Snapshots (32-bit, 64-bit): basic GP binaries built daily from the master branch. Bleeding edge !

MacOS, binary distributions

Basic DMG for MacOS (no packages)

Full DMG for MacOS (all packages)

Snapshot from our GIT server a basic GP binary built daily from the master branch.

Android, binary distributions


The GP to C compiler translates GP scripts to PARI programs.


  • The GNU readline library provides line editing under GP, an automatic context-dependent completion, and an editable history of commands.
  • The GNU MP library can be used as a replacement for the native multiprecision kernel. It is rather faster than the native kernel (benchmarks).
  • The PariEmacs package. Require PARI/GP-2.4.1 and up. GP can be run in an Emacs buffer, with all the obvious advantages if you are familiar with this editor. This package was developped alongside PARI/GP for a long time. It is now developped independently and must be downloaded separately. (In particular, PARI/GP and PariEmacs may be upgraded independently.)

  • perl (used by the gphelp script) provides extended online help (full text from this manual) about functions and concepts, which can be used under GP or independently.


The complete PARI/GP archive with older versions is available via HTTP or FTP.
