Updated by S_H_ (Shun Hiraoka) over 3 years ago

Improve performance some Float methods(write in Ruby) 

 benchmark: 

 ```yml 
 prelude: | 
   flo = 4.2 
 benchmark: 
   to_f: | 
     flo.to_f 
   abs: | 
     flo.abs 
   magnitude: | 
     flo.magnitude 
   -@: | 
     -flo 
   zero?: | 
     flo.zero? 
 loop_count: 20000000 


 ``` 

 result: 

 ```bash 
 sh@DESKTOP-L0NI312:~/rubydev/build$ make benchmark/float_methods.yml -e BENCH_RUBY=../install/bin/ruby -e COMPARE_RUBY=~/.rbenv/shims/ruby
