Decimal work plan

[littledan]

We plan to present Decimal for Stage 1 at the February 2020 TC39 meeting. To get to Stage 2, it will be useful to accomplish the following tasks to further investigate both options:

• BigDecimal
  • Write complete reference documentation with examples
  • Implement a JSBI-style polyfill (JSBI-style polyfill: Volunteers wanted! #17) "JSBD"
  • Wrap the JSBD polyfill in a style using the operator overloading proposal
  • Write some larger, more realistic code samples (Add code samples to the README #34)
  • Write spec text
• Decimal128
  • Write complete reference documentation with examples
  • Implement a JSBI-style polyfill (JSBI-style polyfill: Volunteers wanted! #17) "JSD128"
  • Wrap the JSD128 polyfill in a style using the operator overloading proposal
  • Write some larger, more realistic code samples (Add code samples to the README #34)
  • Write spec text
• Implement Decimal literal syntax in Babel (Babel PR for BigDecimal syntax: volunteers wanted #18)
• Scrub all bugs about semantic questions and ensure that we have good, initial answers
• Survey use cases and environment interactions more thoroughly and document results
• Determine which rounding modes and standard library functions to include

I plan to work on these, but there's a lot to do, and I could use help. If you want to get involved, feel free to respond to this issue; we can use it to coordinate task ownership.

I've tagged the implementation bugs with pointers to bignumber.js, which may have a lot of what you need to get started.

What's the status of the progress? When we can go to stage3?

We're still at stage 1. Stage 2 is possible this year, but probably not stage 3.
