ISO is not a source for mathematical definitions

It's a definition from a well-respected global standards organization. Can you name a source that would provide a more authoritative definition than the ISO?

There's no universally correct definition for what the ≈ symbol means, and if you write a paper or a proof or whatever, you're welcome to define it to mean whatever you want in that context, but citing a professional standards organization seems like a pretty reliable way to find a commonly-accepted and understood definition.

A) knew there was an iso standard

  1. went to the effort of locating it

iii) posted it in respectful manner, and

e) are correct.
