I agree with this. One of the biggest mistakes some languages take is
to not expose the floating point architecture. So at the lowest level,
totally expose the floating point part of the machine with all of the
IEEE options, if any, and then we can design and build the complete
numeric tower as the level 2 addition to the language.

My opinions are barely my own. Clearly Digital wants nothing to do with them
