Where 7231 fits
Why 7231 is special
It is one of six documents that replaced RFC 2616, and the split is why a modern citation names a specific aspect of HTTP rather than the protocol as a whole.
Not just a mathematical number
7231is also used in ways where ordinary arithmetic doesn't apply — each listed below with what genuinely does and doesn't follow from it.
- Mathematical number
A genuine quantity — its mathematical properties (prime, square, factors, and so on) are real facts about it.
A genuine quantity that ordinary arithmetic applies to — it can be prime, even, a perfect square, added to another number meaningfully, and so on.
- Code
Also used as a code — HTTP status codes.
An assigned identifier from a fixed registry or standard — its digits don't represent an amount, and arithmetic on it is meaningless (HTTP status 404 + 1 is not a 'better' status; it's a different, unrelated code).

Hexadecimal

1 × 4,096 + c × 256 + 3 × 16 + f × 1 = 7,231
Read as powers of two: 4,096 + 2,048 + 1,024 + 32 + 16 + 8 + 4 + 2 + 1 = 7,231.
In historical numeral systems
Egyptian
7 lotuses, 2 coils of rope, 3 hobbles, 1 stroke
7 × 1,000 + 2 × 100 + 3 × 10 + 1 × 1 = 7,231. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Technology & computing
RFC 2616 was replaced by six documents in 2014, of which 7231 covers semantics and content. Citing HTTP now means citing a part of it, which is a direct consequence of the original being too large to keep consistent.
