Precise fractional arithmetic for PostgreSQL
pg_rational implements precise fractional arithmetic for PostgreSQL. Perfect for exact arithmetic or user-specified table row ordering. Holds values as big as an integer, with matching precision in the denominator.
Features:
* Stores fractions in exactly 64 bits (same size as float) * Written in C for high performance * Detects and halts arithmetic overflow for correctness * Uses native CPU instructions for fast overflow detection * Defers GCD calculation until requested or absolutely required * Supports btree and hash indices * Implements Stern-Brocot trees for finding intermediate points * Coercion from integer/bigint/tuple * Custom aggregate
