Clast.DatabaseDecimal

Fixed-point decimal arithmetic for database engines, with mantissa tiers from 32 to 256 bits and SQL/Substrait precision-and-scale promotion rules built in.

NuGet CI License: Apache 2.0

Overview

Clast.DatabaseDecimal provides the numeric primitives a query engine or columnar runtime needs to implement SQL NUMERIC(p,s) faithfully:

  • Four mantissa tiers — Decimal32, Decimal64, Decimal128, and Decimal256, covering precisions of 1–9, 10–18, 19–38, and 39–76 digits respectively. The right tier for a given precision is selected by DecimalType.Width.
  • Scalar and span kernels for add, subtract, multiply, divide, and modulus. The span (columnar) kernels operate over ReadOnlySpan<T> / Span<T> for batch evaluation without per-row allocations.
  • UTF-8 and UTF-16 parsing and formatting via DecimalText, with culture-invariant round-tripping.
  • SQL Server / Substrait promotion rules in DecimalTypeRules, so (p1,s1) ⊕ (p2,s2) yields the same result type a database planner would produce.

Example

using Clast.DatabaseDecimal;
using Clast.DatabaseDecimal.Text;
using Clast.DatabaseDecimal.Values;

var type = DecimalType.Numeric(precision: 18, scale: 4);

var a = DecimalText.ParseDecimal64("1234.5678", type.Scale);
var b = DecimalText.ParseDecimal64("0.0001", type.Scale);

var sum = new Decimal64(a.Mantissa + b.Mantissa);
Console.WriteLine(sum.ToString(type.Scale)); // 1234.5679
