Generate Benchmark

Generate a mitata benchmark file for the

{{ category }}

category.

Project Conventions

This project uses mitata for benchmarking. Follow the patterns in

bench/

.

Setup Import

Always import the shared setup:

import { run, bench, group, baseline } from "mitata";
import {
  Decimal,
  decimalJs,
  bigJs,
  bignumberJs,
  dineroAmount,
} from "./setup";

Benchmark Structure

// Group related benchmarks
group("{{ category }} - operation name", () => {
  // Always include baseline (usually Decimal or native)
  baseline("Centimal", () => {
    // benchmark code
  });

  // Compare against other libraries
  bench("decimal.js", () => {
    // equivalent operation
  });

  bench("big.js", () => {
    // equivalent operation
  });

  bench("bignumber.js", () => {
    // equivalent operation
  });
});

// Run all benchmarks
await run();

Example Pattern (from arithmetic.bench.ts)

group("addition - small numbers", () => {
  baseline("Centimal", () => {
    Decimal.from("123.45").add(Decimal.from("67.89"));
  });

  bench("decimal.js", () => {
    decimalJs("123.45").plus("67.89");
  });

  bench("big.js", () => {
    bigJs("123.45").plus("67.89");
  });

  bench("bignumber.js", () => {
    bignumberJs("123.45").plus("67.89");
  });
});

Test Data Recommendations

Category	Test Cases
Arithmetic	Small numbers, large numbers, high precision
Parsing	Integers, decimals, scientific notation, edge cases
Comparison	Equal, not equal, less than, greater than
Percentage	Small %, large %, fractional %
Allocation	2-way split, 3-way split, uneven ratios

Output Location

Create:

bench/{{ category }}.bench.ts

Your Task

1. Read existing benchmarks in

   bench/

   to understand patterns
2. Read

   bench/setup.ts

   to understand available test fixtures
3. Create

   bench/{{ category }}.bench.ts

   with comprehensive benchmarks
4. Ensure the new file is imported in

   bench/run.ts

   if needed
