analyze_tolerance
Kind: Function
Domain: Expressions, units, and tolerances
Canonical import: from cadflow import analyze_tolerance
Signature
def analyze_tolerance(value: 'ScalarLike', *, method: 'ToleranceMethod' = 'worst_case') -> 'ToleranceAnalysis'
Description
Propagate source manufacturing tolerances through a scalar expression.
Propagate source manufacturing tolerances through a scalar expression.
worst_case returns guaranteed interval bounds. Affine chains are dependency-aware, so repeated variables such as x - x cancel exactly; nonlinear chains use conservative interval arithmetic. rss performs a first-order root-sum-square calculation using analytic sensitivities.
Unit-aware variables are converted to canonical CAD units before propagation. The returned analysis reports the inferred physical dimension and canonical result unit. Every variable in the expression must declare a source tolerance.
Parameters
| Name | Type | Required | Default | Source description |
|---|---|---|---|---|
value | 'ScalarLike' | yes | - | Not explicitly described in the source docstring. |
method | 'ToleranceMethod' | no | 'worst_case' | Not explicitly described in the source docstring. |
Returns
Type: 'ToleranceAnalysis'
The source docstring does not declare additional return semantics.
Errors
The source docstring does not declare a narrower exception contract. Invalid types, values, ownership, paths, or backend state may still raise the corresponding public error.
Behavior and constraints
- The contract below is generated from the current public runtime signature. Check domain notes for ownership and workflow constraints.
