如何获取标准golang软件包的版本并进行更新？

Question

I looked into go list but couldn't find a flag that does this. https://golang.org/pkg/math/ has a Round function but it's not found in my local install.

Answer 1

golang.org always documents the latest released version of Go. See https://golang.org/doc/devel/release.html for the release notes. math.Round was introduced in 1.10.
