Free for the community
Accumath, the math engine, is proprietary. While we build it, we are also building pure-Rust tools and giving them to the community for free under the MIT or Apache-2.0 license. Each project below has its own page listing what is built and tested, and what is still to build.
Arbitrary-precision floating point done entirely in software.
26 capabilities built and tested.
Pure-Rust LaTeX math renderer to SVG, PNG, or egui.
18 capabilities built and tested.
Pure-Rust HDF5 reader and writer with no C library.
15 capabilities built and tested.
Browse redb databases from Rust.
5 capabilities built and tested.
Headless notebook core: cells, dependency graph, jobs, and save files.
13 capabilities built and tested.
Interval (ball) arithmetic with rigorous error bounds, built on zenith-float.
18 capabilities 13 built and tested.
Accumath — the SoftFloat hybrid computer algebra engine, equation library, and paid lifetime license — is not open source and is not on crates.io. It stays 100% pure Rust: no Python, C, or other foreign bindings inside the engine. Language wrappers live only on the open accu_book notebook, not in Accumath. AccuMathLab and later commercial products stay proprietary unless we say otherwise.
