Ticket #2099 (closed proposal: wontfix)
Storable instance for Complex

I propose that the following instance be added to base:
instance (RealFloat a, Storable a) => Storable (Complex a) where sizeOf z = 2 * sizeOf (realPart z) alignment z = sizeOf (realPart z) peek p = do [r,i] <- peekArray 2 (castPtr p) return (r :+ i) poke p (r :+ i) = pokeArray (castPtr p) [r,i]
This instance is binary compatible with C99, C++ and Fortran complex types.
It is currently needed by at least two independent packages: hmatrix and fft. Since it is natural for user code to use both of these packages, we need to move the instance to a common location.
