This is part of the mds/mcs consolidation that Ezra approved on 2026-11-02. It was split from Morrison-Lab/mds#565 to keep each PR under the size cap. The two PRs touch different parts of _number-systems.qmd and references.bib, so they can merge in either order.

What changes

• Number systems page, after the real numbers:
  • def-floor, the floor of a real number.
  • exm-floor, with a staircase figure.
• Algebra page, after the real power:
  • def-logarithm, for any base b > 0 with b ≠ 1.
  • exm-logarithm, with a figure of log₂ x.
  • rem-logarithm-formula, which derives log_b x = ln x / ln b and so shows the value is unique. This answers a review point on Add divisibility, primes, congruence and factorial #565.
• references.bib: adds wikipedia_floor_ceiling.

The ids are the same as in the mcs CSCI 201 notes, so mcs can include these files without changing its links.

Checks

• check-term-links, check-new-line-breaks (on *.md and *.qmd) and check-exm-figures pass locally against origin/main.
• Both pages now have R figure chunks. This session has no rmarkdown, so CI is the first render of the figures.

Addressed the review in the latest push:

• Forward reference (blocking): rem-logarithm-formula now comes right after thm-exp-log-inverse, so it no longer cites a theorem the reader hasn't reached.
• Which part of the theorem: the remark now proves the equivalence both ways. Part 1 covers "if $y \log b = \log x$, then $\exp(y \log b) = x$". Part 2 ("apply $\log$ to both sides") covers the converse.
• Final formula: the remark now states $\log_b x = \log x / \log b$ as a display equation.
• Line break: "Since $b \ne 1$," is now on its own line.
• \log_b macro: the shared macro library has no base-$b$ logarithm macro, so \log_b stays raw for now. If one is wanted, it belongs in Morrison-Lab/macros, not here.

@claude review

The automatic review on 283fedd was skipped after its run was preempted, so this head has no verdict yet.

I fetched PR #566 live just now. It is open, not a draft and not merged (mergedAt is null). Its head is 1e82617a02a5deb74310d3efa1a8463dfa6dacf3, the commit I reviewed, so the review above still applies.

Cross-model review waived for head 1e82617: OpenCode Go returned HTTP 429 (GoUsageLimitError, monthly limit) at 00:50 UTC for deepseek-v4-pro, kimi-k3, qwen3.8-max and glm-5.3, and the network proxy refuses ollama. The Claude review of 1e82617 is Ready for merge, every check is green, the head is current with main, and check-pr-fully-clean passes. Ezra granted mwc for this PR in the project thread.
