Understanding IEEE‑754 Floating‑Point Precision Issues in JavaScript
This article explains why JavaScript’s Number type, which follows the IEEE‑754 double‑precision standard, can produce unexpected results such as 0.1 + 0.2 = 0.30000000000000004, demonstrates the binary representation of numbers like 2.5 and 0.1, and offers practical techniques and libraries to mitigate floating‑point errors.
