He meant 16-bit floats, which have sizeOf 2
On GPUs this is common and implemented in hardware (at least on the old GPUs).
On DPSs you commonly had 24-bit floats too.
But these days I guess 32-bit is the minimum one would want to use? Most of the time I just use double anyway :)
What about the built-in Float type?
Prelude Foreign.Storable> sizeOf (undefined :: Float)
4
Prelude Foreign.Storable> sizeOf (undefined :: Double)
8
Or maybe you mean something that can be used with FFI calls to C, in which case Foreign.C.Types (CFloat).
Both instance the Floating, RealFloat, RealFrac, etc, classes so should operate largely the same as (modulo precision) a Double.

Hi guys,
Do we have anything like half precision floats in Haskell? Maybe in some non standard libraries? Or I have to use FFI + OpenEXR library to achieve this?
Cheers,
