Interpreting results
If cube of sum looks implausible, re-check units and which field is optional vs required.
Assumptions
- The wired execution function for `cube-of-sum-calculator` is the source of numerical behavior.
- Inputs for `cube-of-sum-calculator` follow the on-page labels; values/shapes must match this operation.
- Real-number arithmetic is used unless cube of sum explicitly needs integers.
Limitations
- Display rounding can differ slightly from a CAS/symbolic exact form of cube of sum.
- Edge cases outside the intended domain of cube of sum may error or look unstable—treat them as out of scope.
- Complex/branch cuts and undefined points are not always interactively annotated for cube of sum.
Important note
