[ruby-core:67912] [ruby-trunk - Feature #10800] [PRRF][PATCH] Make math.c twice as faster when passed Bignum
From:

ruby-core #67912
Issue #10800 has been updated by gogo tanaka.
Hi! After r49449, I found math.c become 5.7 times faster than before.
note: in a certain case (`Math.atan2 ` with `Fixnum`)
In almost all case, every function become about 3 times faster than before.
(And now Ruby's math module faster than python's one in my benchmark, but w=
e don=E2=80=99t need to care about it so much)
# math.c with Fixnum(1)
```

I leave code which measures this benchmark here(https://gist.github.com/gog=
otanaka/379b00397d494a2b22d2)
I'm gonna do same thing for `Rational` and produce more proper and general =
benchmark.

Feature #10800: [PRRF][PATCH] Make math.c twice as faster when passed Bignum

----------------------------------------
This ticket is continued from [Feature 10785](https://bugs.ruby-lang.org/i=
ssues/10785)
My patch last time is only for Fixnum, but now I'd like to do same thing fo=
r Bignum without loosing others performance.
And this time I follow [r49434](https://bugs.ruby-lang.org/projects/ruby-tr=
unk/repository/revisions/49434) not to ignore redefinition of Integer#to_f =
;)
thanks.
