Worked Example
Verified calculation
Given:
- Allocated Stack Size = 1024
- Measured Peak Stack Usage = 768
Expected Result:
- Stack Safety Margin Ratio = 0.25
Engineering Interpretation:
Under the given input conditions, the calculated result is: Stack Safety Margin Ratio = 0.25 dimensionless.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
