Floating‑point arithmetic
Floating‑point arithmetic is a method of approximating real‑number calculations on digital computers using finite precision formats defined by standards such as IEEE 754 (2019) and its international adoption ISO/IEC 60559:2020. It specifies binary and decimal formats, rounding rules, special values, status flags, and required operations used by most modern hardware and software environments.
