The last couple generations of POWER chips from IBM have implementations of decimal32, decimal64, and decimal128. To my knowledge, no other big-name, general-purpose CPU has these. To "implement decimal numbers" in .net on x86 hardware simply means writing a custom decimal implementation in software. JS had implicit integers since the beginning. It has had arrays of integers (what's necessary for fast decimal implementations) since BEFORE the release of WebGL a decade ago. It has also added BigInt this year. Just like .net, there's decimal libraries available if you know to use them. https://github.com/MikeMcl/decimal.js/ https://github.com/MikeMcl/decimal.js/ The real takeaway is that modern processors should definitely add hardware support for decimal numbers.
