Crate bicmath_core 

BicMath core: the shared numerical contract.

This crate owns:

• number: exact integers, rationals, decimals, and explicit f64.
• value: the recursive wire value model (quantities, money, matrices).
• error: stable error codes and structured errors.
• limits: resource limits and cooperative cancellation.
• context: execution and numeric contexts.
• schema: typed parameter/output schemas and validation.
• contract: module and function descriptors, the contract::Function trait.
• envelope: the versioned result envelope.
• fingerprint: canonical encoding, fingerprints, and replay receipts.
• expr: the restricted expression grammar and parser (no function resolution).

No transport, async runtime, filesystem, clock, or network code lives here.

Modules

context

Execution and effective numeric contexts.

contract

Module and function contracts, invocation arguments, and outcomes.

envelope

The versioned result envelope shared by every adapter.

error

Stable error codes and structured errors.

eval

Shared restricted-expression evaluators.

expr

The restricted expression grammar and parser.

fingerprint

Canonical encoding, deterministic fingerprints, and replay receipts.

limits

Resource limits and cooperative cancellation.

number

Numeric representations and the promotion/conversion contract.

schema

Typed parameter and output schemas with shared validation semantics.

value

The recursive wire value model.

Constants

NUMERICAL_POLICY_VERSION

Version of the numerical policy semantics (rounding defaults, promotion rules, quantile conventions). Bump this whenever a semantic change could alter a downstream financial or statistical result, even if Rust types are unchanged.

VERSION

Crate version, as compiled.

WIRE_SCHEMA_VERSION

Version of the public wire schema produced by this engine.
