The big and Small of JavaScript numbers (2017) (fluffyandflakey.blog)
For all its warts, JavaScript has some novelties few other languages have. In this post I want to share about JavaScript numbers, which both acknowledge normal mathematics and the fact that they are represented by an imperfect data format.

Fixed-point arithmetic as a replacement for soft floats (pigweed.dev)
Fixed-point arithmetic is an alternative to floating-point arithmetic for representing fractional data values (0.5, -1.125, 10.75, etc.). Fixed-point types can be represented as scaled integers. The advantage here is many arithmetic operations (+, -, *, /, etc.) can be implemented as normal integral instructions. This can be useful for embedded systems or other applications where floating-point operations can be too expensive or not available. Clang has support for fixed-point types according to ISO TR 18037.
