How the Slovenia letno nadomestilo calculator is verified
Inputs
| Input | Field | Type |
|---|---|---|
| Prostornina motorja (cm³) | cc | number |
The formula
Each derived value below is computed by the Valem engine from the expression shown, in this order. Nothing else runs — there is no hidden code path.
| Derived value | Field | Formula (JSONata) |
|---|---|---|
| Letno nadomestilo | tax | ($c := cc; $round($c <= 1350 ? 62 : $c <= 1800 ? 96 : $c <= 2500 ? 153 : $c <= 3000 ? 282 : $c <= 4000 ? 452 : 565, 2)) |
Test vectors (3)
Every case is executed against this model on each build, by the Java engine and independently by a JavaScript one. A mismatch of a single cent fails the build, so the page cannot ship advertising a figure the model no longer produces.
Case 1 — C1 1.598 ccm — razred do 1.800 ccm
given cc | 1598 |
|---|---|
expect tax | 96 |
Case 2 — C2 2.000 ccm — razred do 2.500 ccm
given cc | 2000 |
|---|---|
expect tax | 153 |
Case 3 — C3 4.200 ccm — najvišji razred
given cc | 4200 |
|---|---|
expect tax | 565 |
