+
+ES2015-compliant shim for Number.isNaN - the global isNaN returns false positives.
+
+This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the [spec](http://www.ecma-international.org/ecma-262/6.0/#sec-number.isnan).
+
+## Example
+
+```js
+Number.isNaN = require('is-nan');
+var assert = require('assert');
+
+assert.notOk(Number.isNaN(undefined));
+assert.notOk(Number.isNaN(null));
+assert.notOk(Number.isNaN(false));
+assert.notOk(Number.isNaN(true));
+assert.notOk(Number.isNaN(0));
+assert.notOk(Number.isNaN(42));
+assert.notOk(Number.isNaN(Infinity));
+assert.notOk(Number.isNaN(-Infinity));
+assert.notOk(Number.isNaN('foo'));
+assert.notOk(Number.isNaN(function () {}));
+assert.notOk(Number.isNaN([]));
+assert.notOk(Number.isNaN({}));
+
+assert.ok(Number.isNaN(NaN));
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`
