Thanks :)
What is wrong with using unsigned here (just performance?)
What was incorrect about my previous mantissa condition?
local lohi_p = ffi.typeof("struct { int32_t "..(ffi.abi("le") and "lo,
> hi" or "hi, lo").."; } *")

Nice trick for an endianess fix :)
Will have to remember this.
I've updated the gist with your code, thanks again for the supervision!
