Decima

A new technical essay explores adding floating-point decimal arithmetic, walking through how to represent and operate on decimals that cannot be stored exactly in standard binary floats. The piece covers the design trade-offs, precision pitfalls, and practical gains of decimal support, and is drawing attention from programmers interested in numerical computing and language design.

A guide covering six common currency mistakes developers make is drawing attention. It covers the pitfalls of using floating-point numbers for money, incorrect decimal place handling, currency symbol confusion, mixing up base and quote currencies in exchange rates, and relying on stale rates. Practical code examples in JavaScript and Python show how to handle money correctly in software, a topic of recurring interest in fintech and web development circles.
