Assumptions
- The wired execution function for `linear-inequality-solver-calculator` is the source of numerical behavior.
- Inputs for `linear-inequality-solver-calculator` follow the on-page labels; values/shapes must match this operation.
- Real-number arithmetic is used unless linear inequality solver explicitly needs integers.
Limitations
- Display rounding can differ slightly from a CAS/symbolic exact form of linear inequality solver.
- Edge cases outside the intended domain of linear inequality solver may error or look unstable—treat them as out of scope.
- Complex/branch cuts and undefined points are not always interactively annotated for linear inequality solver.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
