I hope to clean it up soon.\n\n\n## Contributing\n\nIf you are a developer and want to help making it better, or a designer who wants to make it look prettier or\nyou know IEEE 754 and can see some error or a field for improvement - let me know by reporting an issue, sending\npull request or contact me at [@bartaz](http://twitter.com/bartaz) on Twitter.\n\n\n## Acknowledgments and Resources\n\nThis tool wouldn't be possible without great work of others.\n\n\n### Learning resources\n\nEverything I know about numbers in IEEE 754 representation I've learnt from resources freely available on-line.\n\nNearly everything about JS numbers is described in details by Axel Rauschmayer in his [this series of articles about numbers](http://www.2ality.com/search/label/numbers), such as:\n\n* [How numbers are encoded in JavaScript](http://www.2ality.com/2012/04/number-encoding.html)\n* [NaN and Infinity in JavaScript](http://www.2ality.com/2012/02/nan-infinity.html)\n* [Safe integers in JavaScript](http://www.2ality.com/2013/10/safe-integers.html)\n\nThere is of course a lot about this topic on Wikipedia. Like this [Double-precision floating-point format](http://en.wikipedia.org/wiki/Double-precision_floating-point_format) article, or description of the [IEEE 754-1985](http://en.wikipedia.org/wiki/IEEE_754-1985) standard.\n\nYou may also want to know what ECMAScript standard has to say about [Number type](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-ecmascript-language-types-number-type).\n\nThis is also not the first attempt to provide visualisation or conversion tools between numbers and their binary representation in IEEE 754 standard.\n\n* [IEEE-754 Analysis](http://babbage.cs.qc.cuny.edu/IEEE-754/index.xhtml)\n* [float.js](http://dherman.github.io/float.js/)\n\n\n### Tools\n\nCreating this visualization would be much harder without great tools such as:\n\n* [webmake](https://github.com/medikoo/modules-webmake/) by Mariusz Nowak\n* [CSS MathML fallback](http://lea.verou.me/2013/03/use-mathml-today-with-css-fallback/) by Lea Verou\n* [Tangle](http://worrydream.com/Tangle/) by Bret Victor and his great work on [explorable explanations](http://worrydream.com/ExplorableExplanations/)\n\n\n## License\n\nCopyright 2013 Bartek Szopka.\n\nReleased under the MIT License.\n","funding_links":[],"categories":["Uncategorized"],"sub_categories":["Uncategorized"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/bartaz.github.io%2Fieee754-visualization%2F","html_url":"https://awesome.ecosyste.ms/projects/bartaz.github.io%2Fieee754-visualization%2F","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/bartaz.github.io%2Fieee754-visualization%2F/lists"}
