This repository defines a high-level Haskell bindings for LibBF, a C library for handling arbitrary-precision floating-point numbers. These bindings are reasonably portable (with the caveats listed in the "Limitations" section) and have been tested to work on Linux, macOS, and Windows.
By default, this library builds a copy of the LibBF source code that is bundled
with the source distribution, which means that you can build this library
without needing to install any external C dependencies. If you wish, you may
also build this library with the +system-libbf flag enabled to instead link
against your operating system's version of LibBF.
The most recent release on the LibBF website
dates back to 2020, which does not support non-x86 architectures (e.g.,
AArch64). For this reason, we instead bundle a more recent of LibBF (written in
2021) that is bundled with the quickjs
library. We may also choose to backport other critical bugfixes if they are
needed.
-
At present, this library only supports 64-bit architectures. If you would like to help get this library running on 32-bit, pull requests are welcome!
-
Not all LibBF operations are currently exposed. For instance, we do not yet expose transcendental functions.
