The GNU Ada runtime uses the largest type for all its floating
point format services (on x86 this means 80-bit floats), it all
boils down to the Set_Image_Real routine in:
It's heavily commented and not that long,
it would be fun to do the same code in mono
and see how it performs against the current one,
any interest in me trying to do this?
