How floating point numbers work in computers and how to implement the IEEE 754 standard from scratch in JavaScript.
Floating point math is tricky. In this video, we'll learn how these numbers work in computers, and build a software implementation from scratch in JavaScript. =[ 🔗 Links 🔗 ]= - ⭐️ Patreon: patreon.com/lowleveljavascript - 💌 Updates to your inbox: tinyletter.com/lowleveljavascript - Floating Point Arithmetic: en.wikipedia.org/wiki/Floating-point_arithmetic - 16 Bit Floats: en.wikipedia.org/wiki/Half-precision_floating-point_format - IEEE 754 Spec: ieeexplore.ieee.org/document/30711 - Fabien Sanglard's awesome blog on the subject: fabiensanglard.net/floating_point_visually_explained/ - Denormalised Numbers: en.wikipedia.org/wiki/Denormal_number - Github Repo: github.com/LowLevelJavaScript/Floating-Point-Implemented-In-…Why it's here
