I could be completely wrong, but I doubt any of my (US) professors would reference an ISO definition, and may not even know it exists. Mathematicians in my experience are far less concerned about the terminology or symbols used to describe something as long as they’re clearly defined. In fact, they’ll probably make up their own symbology just because it’s slightly more convenient for their proof.

My experience (bachelor's in math and physics, but I went into physics) is that if you want to be clear about including zero or not you add a subscript or superscript to specify. For non-negative integers you add a subscript zero (ℕ_0). For strictly positive natural numbers you can either do ℕ_1 or ℕ^+.

I hate those guys. I had that one prof at uni and he reinvented every possible symbol and everything was so different. It was a pita to learn from external material.

I feel so thoroughly called out RN. 😂

From what i understand, you can pay iso to standardise anything. So it's only useful for interoperability.

[–] [email protected] 2 points 10 months ago (1 children)

Yeah, interoperability. Like every software implementation of natural numbers that include 0.

How programmers utilize something doesn't mean it's the mathematical standard, idk why ISO would be a reference for this at all

[–] [email protected] 1 points 10 months ago (1 children)

Because ISO is the International Organisation for Standardization

Yes, but it's not for mathematicians. It's for the applied fields.

Can I pay them to make my dick length the ISO standard?

[–] [email protected] 6 points 10 months ago

I feel they have an image to maintain, but i also feel they would sell out for enough money. So.. tell me if you make it.

[–] [email protected] 1 points 10 months ago

Yeah dont do that.
