Use Rational for Float#round with ndigits > 14 2021-08-06T22:03:51+00:00 Jeremy Evans code@jeremyevans.net 2021-07-26T18:20:27+00:00 d16b68cb2204eeb5af8bd39149202b630374c67f ndigits higher than 14 can result in values that are slightly too large due to floating point limitations. Converting to rational for the calculation and then back to float fixes these issues. Fixes [Bug #14635] Fixes [Bug #17183] Co-authored by: Yusuke Endoh <mame@ruby-lang.org>

cdhash_cmp: can take rational literals 2021-05-12T01:30:46+00:00 卜部昌平 shyouhei@ruby-lang.org 2021-05-07T01:04:08+00:00 2bc293e899c9d32dcd794a73de8925c49ecf8f15 Rational literals are those integers suffixed with `r`. They tend to be a part of more complex expressions like `123/456r`, but in theory they can live alone. When such "bare" rational literals are passed to case-when branch, we have to take care of them.

According to MSVC manual (*1), cl.exe can skip including a header file
when that:

- contains #pragma once, or
- starts with #ifndef, or
- starts with #if ! defined.

GCC has a similar trick (*2), but it acts more stricter (e. g. there
must be _no tokens_ outside of #ifndef...#endif).

Sun C lacked #pragma once for a looong time.  Oracle Developer Studio
12.5 finally implemented it, but we cannot assume such recent version.

This changeset modifies header files so that each of them include
strictly one #ifndef...#endif.  I believe this is the most portable way
to trigger compiler optimizations. [Bug #16770]
