Description
FFI bindings for C long double.
Description
This package provides a LongDouble type, being 80bits of x87 data taking up 96bits on i386 and 128bits on x86_64. On arm it is an alias for 64bit double. On aarch64 it is an alias for quadruple precision _Float128, except under Apple macOS or Microsoft Windows where it equals double. It does not provide a CLDouble type usable for FFI without wrapping in Ptr, this needs to be done by the compiler. See https://ghc.haskell.org/trac/ghc/ticket/3353.
