GitHub CI Build Status

This is a Julia interface to libquadmath, providing a Float128 type corresponding to the IEEE754 binary128 floating point format.


Quadmath currently works on x86_64 Linux, macOS, and Windows.

  • It may require a new-ish version of gcc which supports __float128 type.
  • It has not been tested on 32 bit Linux.
  • It does not work on ARM due to the lack of libquadmath support for that platform.


Quadmath.jl is now a registered package, so can be added via ]add Quadmath.


Thank you to Harald Hofstätter, who provided the first iteration of Quadmath.jl.
