Node Interactive North America 2016

The built-in JavaScript Math library is used in virtually every Node.js application, from generating random ids to calculating exponential back-off times to computing basic performance metrics. When using the Math library, most developers simply assume that the underlying implementations are accurate, performant, and correctly implemented. In this presentation, Athan Reines will discuss why this assumption is often false and show the various ways in which the standard library is broken. 

The presentation will present the algorithms used, their performance and accuracy, and how they have downstream effects on users of these libraries. The presentation will conclude by highlighting how community solutions are stepping up to fix these problems and identity opportunities for additional improvements.
