Oh sorry, I misread the original question. I take it all back!

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?

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.
