@jdsalasc/solvejs-numbers

Zero-dependency number utilities for JavaScript and TypeScript.

Utilities

• clamp, roundTo, sum, average, median
• percent, percentChange
• safeDivide, isBetween
• toCurrency, toNumber, randomInt

When to use this package

Use it when you need safer business math and robust number parsing for forms, analytics, and pricing logic.

Limitations and Constraints

• Results use IEEE-754 floating-point arithmetic.
• Money workflows should enforce explicit rounding boundaries per domain rules.

Install

npm i @jdsalasc/solvejs-numbers

Quick example

import { toNumber, safeDivide, percentChange } from "@jdsalasc/solvejs-numbers";

const revenue = toNumber("12,500");
const ratio = safeDivide(50, 0, 0);
const growth = percentChange(120, 100); // 20

Precision note

JavaScript numbers are floating-point. For money-sensitive flows, apply explicit rounding steps (for example roundTo(value, 2)) at domain boundaries (tax, subtotal, invoice total).
