mathlib-fp v1.9.2

Version 1.9.2 makes the stable 1.9 breadth easier to learn without changing the frozen public API. The primary teaching path uses double-real data and simple allocating calls; single precision, complex values, views, destinations, reusable factors, and workspaces remain clearly linked advanced steps.

Beginner learning path

• The beginner guide introduces Free Pascal dynamic arrays, zero-based indexing, managed interface lifetimes, callbacks, options records, iteration statuses, invalid-contract exceptions, allocation, and precision choices.
• The recipe index covers dense and sparse solves, descriptive and streaming statistics, normal probability, interpolation and fitting, optimisation, FFT convolution and filtering, time series, finance, geometry, and unit conversion.
• Every stable domain landing page now starts with a tested beginner route, common-task selection table, exact contract/failure links, allocation and precision guidance, and a tested advanced route.
• Common entry points appear before compatibility or implementation scaffolding, so ordinary double-real programs do not require generic, destination-buffer, or workspace knowledge.

Search and executable documentation

• Generated documentation search is checked for problem phrases including “least squares”, “normal probability”, and “FFT convolution”, even when the reader does not know a Pascal identifier.
• Release checks require an output-checked runnable beginner program for all 13 stable domains. All published recipe code and claimed output are compiled and run from the clean source archive.
• The automated beginner-journey contract verifies search discovery, route links, runnable code, claimed output, release identity, and public declarations from checksummed clean archives.

Install

Download the tagged source as .tar.gz or .zip, extract it, and compile the README program with src/ on the unit search path. No configure step, network access, foreign binary, or third-party runtime package is required.

Compatibility and limitations

The checked public-api-1.9.json snapshot and all 2,880 owner/signature-aware declaration rows remain unchanged from 1.9.0. Version 1.9.2 adds no public type, algorithm family, overload, default, deprecation, storage rule, or implicit conversion. Existing 1.9 source remains compatible, and the limitations in the capability inventory are unchanged.
