 SQL also has `NUMERIC`/`DECIMAL` as a built-in type, predating many programming languages.
 
 Many languages added decimal support 10+ years ago. The IEEE 754-2008 standard for Decimal128 is now 17 years old. (The 2019 edition of IEEE 754 also has decimal arithmetic.)
- Indeed, multiple numeric types are not unusual. Languages ship with integers, floats, *and* decimals. Python even includes both decimals and rationals. The existence of JS's `Number` and `BigInt` doesn't preclude `Decimal`. Moreover, the need for decimal types across many languages reflects a genuine, universal need rather than a niche requirement.
 
-### Why JavaScript Lacks Decimal Support

However, JavaScript's role has fundamentally changed. Back in the 1990s, JS was focused on form validation and DOM manipulation. Now we have full-stack applications, including financial systems, e-commerce platforms, serverless backends, and data processing pipelines.

-Compare this to BigInt: before native support, polyfills and userland big integer libraries had minimal adoption because the *need* was niche. Decimal libraries show massive adoption because the need is universal.

-Thus, Decimal standardizes existing practice. Developers are already using decimal libraries (millions of downloads/week), converting numbers to "cents" (error-prone, confusing), using `Number` incorrectly (causing bugs). Decimal doesn't ask developers to adopt something new; it offers a better way to do what they're already struggling to do.
