def analyze_tolerance(value: 'ScalarLike', *, method: 'ToleranceMethod' = 'worst_case') -> 'ToleranceAnalysis'
功能说明
analyze_tolerance 是 CadFlow 表达式、单位与公差领域的公共函数。
原始 API 说明
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.
