The latest Toolcore batch adds another hundred browser-local pages in chi-square and t-test demos, matrix and sequence math, Morse and readability tools, hash and CRC checksum demos, octal and HTML entity encoding, HTTP ETag and Link header parsers, Julian day helpers, and IBAN/NPI format checks. Use this map when you know the job—not when you want to scroll the full catalog.
Hypothesis tests, confidence intervals, and matrices
- Chi-square contingency (lite), Welch t-test (lite), and mean Z confidence interval — quick checks on pasted comma lists.
- 2×2 matrix transpose, binomial coefficient nCr, and Fibonacci sequence list — homework-friendly math without a spreadsheet.
- Loan payment estimate, break-even units, and ROI percent (lite) — intro finance drills beside the calculators hub.
Readability, Morse, and word tools
- Flesch reading ease, Gunning fog index, and automated readability index — grade-level estimates from pasted prose.
- Morse encode (lite), Caesar decode with shift, and anagram check — puzzle and classroom cipher helpers.
Hash demos and encoding variants
- SHA-1 demo digest, Adler32 demo, and CRC-16 CCITT demo — checksum homework without leaving the browser.
- Octal text encode, HTML entity encode, and Base64url decode (lite) — encoding variants beside the main Encoding hub.
HTTP headers, calendar math, and identifiers
- ETag header parse, Accept-Language q-values, and Link header rel parse — split response headers from curl output.
- Julian day number, ISO week year, and days between dates — calendar math beside the timestamp hub.
- IBAN mod97 check, NPI Luhn check, and ISRC format check — identifier checksums next to existing LEI and GTIN tools.
