2019-12-26decouple internal.h headers卜部昌平
Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies).

2019-12-24[DOC] Fix wording in Math::E documentationMarcus Stollsteimer
2019-11-19make functions static卜部昌平
These functions are used from within a compilation unit so we can make them static, for better binary size. This changeset reduces the size of generated ruby binary from 26,590,128 bytes to 26,584,472 bytes on my macihne. Notes: Merged: https://github.com/ruby/ruby/pull/2682
2019-08-29Add word "Euler's number" to Math::E docsschneems
When searching for this constant, I landed on the correct page https://ruby-doc.org/core-2.6.4/Math.html however I was using CMD+f to search for "Euler" and did not find it. If we add the full name for this constant then it will be easier to search for and find. Notes: Merged: https://github.com/ruby/ruby/pull/2411

2018-01-19INFINITY is float. That of double is HUGE_VAL.shyouhei
