Examples
Container internal length: 100
Container internal width: 80
Container internal height: 60
Item external length: 30
Item external width: 20
Item external height: 10
Limitations
- Positive internal container and external item dimensions in the same unit. No padding/weight limit,mixed orientations or global bin-packing optimization. Exact decimal floor counts<=1e9;report all6orientation grids,maximum simple-grid count,used/unused volume and stable best orientation. No clearance guarantee.
- Scalar controls accept explicit finite decimal syntax;positive values normally1e-12–1e12,nonnegative0–1e12 unless a narrower range is stated. JSON numeric rows use finite IEEE754 values within their stated bounds. Derived counts above1billion and nonfinite results refuse. Combined input<=400000UTF8 bytes;complete JSON<=4MiB.
