- Developers needing deterministic cross-platform numerical computation
- Worth noticing
- The page reports matching state digests across four compilers, three operating systems, and two CPU architectures after 100 million steps.
Field notes
The compiler is described as self-hosting: cint compiles itself and targets standard C. The homepage’s orbital example uses checked integer operations, then contrasts its reported identical digest across four compiler builds with a double-precision version said to diverge by 93 cm; the project labels itself experimental and warns that breaking changes may precede 1.0. The source and specifications are linked.
