Date: 2026-08-09 08:58 Summary: Shipped Omni §12 #25–#32 (eight calculators) serially with full coverage/build/lint pipeline; catalog now 84.
[question] In /Users/xuli/vscodeai/onlinefreetools ship EIGHT tools SERIAL with full pipeline each (0b→2→locales→4→all→build:site→lint:seo→isolation CROSS_TOOL_UPDATE=1; inventory+README updates; brief work-tasks). Independent ten-locale rewrites required. NOT YMYL unless noted. Tools #25–#32: z-score, sample-size, significant-figures, scientific-notation, logarithm, pythagorean-theorem, slope, exponent.
[try to solve]
Eight tools shipped serially (each passed coverage 0b/2/4/all, build:site, lint:seo, and CROSS_TOOL_UPDATE=1 isolation). §9/§12 and Omni TSV marked live; README EN/ZH lists updated; after #28 shipped, #27 related links became scientific-notation + z-score.
Sample one-liners:
- z-score: x=85, mean=70, sd=10 → z=1.5
- sample-size: 95% (Z=1.96), p=0.5, E=0.05 → n≈385
- significant-figures: count 0.00304 → 3; round 1234.56 to 3 → 1230 / 1.23e3
- scientific-notation: 12300 → 1.23×10^4
- logarithm: log10(1000)=3
- pythagorean: a=3, b=4 → c=5
- slope: (1,2)(3,6) → 2
- exponent: 2^10=1024
Final catalog: 84
