Which one should I pick for a new project?

I can only answer questions about shopspring/decimal or unknwon/the-way-to-go_zh_cn.

If you're asking which repository to learn from or use, I can help clarify:

• shopspring/decimal is a Go library for arbitrary-precision decimal arithmetic. Use it if you need to perform precise financial calculations or work with decimal numbers in Go.
• unknwon/the-way-to-go_zh_cn is a Chinese-language educational eBook about Go programming fundamentals. Use it if you're learning Go and prefer Chinese documentation.

However, I must note a critical concern: according to RepoPilot's analysis, shopspring/decimal has an OpenSSF Scorecard rating of 3.4/10 and is flagged as unmaintained. This means:

• Token-Permissions: 0/10
• Pinned-Dependencies: 0/10
• CII-Best-Practices: 0/10

If you need decimal arithmetic for production use, the README explicitly recommends alternatives like cockroachdb/apd (more performant) or govalues/decimal (high performance, zero-allocation) [shopspring/decimal README.md:L67-L77].

If you're building a new Go project, start with learning fundamentals from unknwon/the-way-to-go_zh_cn, then evaluate decimal libraries based on your specific performance and maintenance requirements.

FOLLOW_UPS:

• What is your project's primary requirement: learning Go or financial calculations?
• Do you need high-performance decimal arithmetic or educational reference material?
• Are you concerned about library maintenance and security practices?
