This module works cross-realm/iframe, and despite ES6 @@toStringTag. ## Example ```js var isNumber = require('is-number-object'); var assert = require('assert'); assert.notOk(isNumber(undefined)); assert.notOk(isNumber(null)); assert.notOk(isNumber(false)); assert.notOk(isNumber(true)); assert.notOk(isNumber('foo')); assert.notOk(isNumber(function () {})); assert.notOk(isNumber([])); assert.notOk(isNumber({})); assert.notOk(isNumber(/a/g)); assert.notOk(isNumber(new RegExp('a', 'g'))); assert.notOk(isNumber(new Date())); assert.ok(isNumber(42)); assert.ok(isNumber(NaN)); assert.ok(isNumber(Infinity)); assert.ok(isNumber(new Number(42))); ``` ## Tests Simply clone the repo, `npm install`, and run `npm test` [1]: https://npmjs.org/package/is-number-object [2]: https://versionbadg.es/inspect-js/is-number-object.svg [5]: https://david-dm.org/inspect-js/is-number-object.svg [6]: https://david-dm.org/inspect-js/is-number-object [7]: https://david-dm.org/inspect-js/is-number-object/dev-status.svg [8]: https://david-dm.org/inspect-js/is-number-object#info=devDependencies [11]: https://nodei.co/npm/is-number-object.png?downloads=true&stars=true [license-image]: https://img.shields.io/npm/l/is-number-object.svg [license-url]: LICENSE [downloads-image]: https://img.shields.io/npm/dm/is-number-object.svg [downloads-url]: https://npm-stat.com/charts.html?package=is-number-object [codecov-image]: https://codecov.io/gh/inspect-js/is-number-object/branch/main/graphs/badge.svg [codecov-url]: https://app.codecov.io/gh/inspect-js/is-number-object/ [actions-image]: https://img.shields.io/endpoint?url=https://github-actions-badge-u3jn4tfpocch.runkit.sh/inspect-js/is-number-object [actions-url]: https://github.com/inspect-js/is-number-object/actions
