We're using Float values anywhere in our Ruby scripts. Have you gotten any troubles with Float? Have you read the article "What Every Computer Scientist Should Know About Floating-Point Arithmetic"? Have you been scolded about issues of floating-point numbers from Ruby committers in redmine.ruby-lang.org? I'm afraid if you think it's difficult to use floating-point numbers. These troubles, difficulties, and tragedies should be removed from Ruby and its communities. I show you the way to solve these issues.
