EvaluationOptions

Symbolica documentation for getting started, symbolic expressions, numerical evaluation, pattern matching, and APIs in Python and Rust.

`EvaluationOptions`

class EvaluationOptions

Requested accuracy and resource limits. Working precision is not achieved accuracy.

Attributes

Name	Description
`boundary_error_strategy`	Supplied-error propagation policy; unavailable proofs retain scalar bounds.
`deformed_propagator_slots`	Zero-based physical denominator slots, never HEPKit edge IDs or ISP slots.
`digits`
`dimension`
`guard_digits`
`mass_mode`	Auxiliary mass placement name; explicit selections retain their slot list.
`pade_degree`	Optional rational approximation degree; absent means Taylor transport.
`residual_arithmetic`	Source-defect arithmetic: ball (default) or adaptive_integer (opt-in).
`series_order`
`workers`
