Mr. Woodgate can really trip my triggers. The mode and ranges are already covered in IEEE754. There was no reason that this should not have been part of 754, as it is now in the community as IEC60559. The committee attempted to call 1788 a 'basic' standard, but the IEEE shoved it back, so they relegated an important basis for ALU design and Computer Science to an isolated, stand-alone standard. And it does NOT cover de-normalized float intervals. Meh.
This is what happens when we allow too many mathematicians into an engineering subject domain. Pitchforks and flaming torches would be appropriate. You can pry my 17 significant decimal digits from my cold, dead hands.
