The author stated:
   "the number required to “exactly print” its value"

This is flat out a monkey wrench that destroys the real-world 
concept of a floating-point value.

He assumes pristine, exact values. This notion of pristine, exact 
values disappears when you start doing calculations.

It's a magic kingdom, constrained to assumptions.

As for Emanuel's posting, I find it good for a chuckle. So the 
binary representations were fine, and they spent years moping 
about with ULP issues in ASCII representations. Look, some of us 
would have fixed that in an afternoon. Enough said.
