Enum NumericComparisonPolicy 

pub enum NumericComparisonPolicy {
    Exact,
    Approximate,
}

Selects exact or floating-projection numeric comparison.

Self::Exact provides deterministic mathematical ordering across numeric representations. Self::Approximate performs a pair-dependent projection and is not transitive, so it must not be used to implement Ord, sort or group values, or construct keys for ordered maps and sets.

This enum intentionally defines a closed policy set. Exhaustive matching is part of its API contract; adding a variant is a deliberate breaking change.

Examples

use qubit_datatype::NumericComparisonPolicy;

assert_eq!(NumericComparisonPolicy::default(), NumericComparisonPolicy::Exact);

Variants

Exact

Preserves exact mathematical values for deterministic ordering.

Approximate

Attempts finite f64 projection when a primitive float participates.

Primitive infinities are ordered separately. If either operand cannot be projected to a finite f64, comparison falls back to the exact path. Projected comparison is not transitive across mixed representations and is therefore unsuitable for Ord, sorting, grouping, or ordered keys.
