+Performance
+-----------
+There is a simple benchmark included comparing raw read/write performance of this library (float), float's fallback for old browsers, the [ieee754](https://www.npmjs.com/package/ieee754) module and node's [buffer](https://nodejs.org/api/buffer.html). On an i7-2600k running node 6.9.1 it yields:
