Er.. No. As I said, it is an ISO standard, and thus exists to 
codify existing practice. That means that  some representatives 
from countries can block decisions. So first the webpage say that 
you may get a domain error. Then it refers to an IEC standard 
from 1989.

The may part is usually there to not make life difficult for 
existing implementations. So the foundation is IEC, but to bring 
all on board they probably put in openings that _MAY_ be used.

This is what you get from standardization. The purpose of ISO 
standardization is not create something new and pretty, but to 
reduce tendencies towards diverging ad hoc or proprietary 
standards. It is basically there to support international markets 
and fair competition... Not to create beautiful objects.

The process isn't really suited for programming language design, 
I think C++ is an outlier.
