Math Extensions Proposal

Champion

Rick Waldron

Status

This proposal is currently stage 1 of the TC39 process.

Motivation

These functions exist in many, many JS libraries either hand rolled or via many modules on npm. Providing them as built-ins serves to pave cow path. Implementations and naming is inconsistent. Several other languages offer these as built-ins.

Java

Python

Racket

Rust
