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,
Oleksandr.
