Assumptions
- Inputs for `ratio-to-percentage-calculator` follow the on-page labels; values/shapes must match this operation.
- Units (when shown) must be consistent across inputs for ratio to percentage.
- Real-number arithmetic is used unless ratio to percentage explicitly needs integers.
Limitations
- Ratio to Percentage Calculator cannot invent missing inputs; incomplete forms stop short of a forged ratio to percentage value.
- Display rounding can differ slightly from a CAS/symbolic exact form of ratio to percentage.
- Complex/branch cuts and undefined points are not always interactively annotated for ratio to percentage.
Important note
