Fenrigis Although we will not cover Scheme from abs to zero? Returns a Duration instance matching the number of hours provided. Still, I think the code could definitely have been written better. It is fidnum as a quick-start guide, something a novice can use to get a non-trivial working knowledge of the language, before moving on to more comprehensive and in-depth texts. Just a moment while we fixnhm you in to your Goodreads account.

It is wrong as of Ruby 2. See the other answer. It is an abstract class whose job is to endow its children Fixnum and Bignum with methods", is it the same as: Integer is an abstract class that defines the interface for its subclasses Fixnum and Bignum and you never instantiate using an abstract class?

The exact same optimizations still exist, but they are treated as "proper" compiler optimizations, i. This is somewhat confusing. Integer is the real class that you should think about. Fixnum is basically a performance optimization that should never have been made visible to the programmer in the first place. Compare this with flonums in YARV, which are implemented entirely as an optimization inside the VM, and never exposed to the programmer.

Basically, Fixnums are fast and Bignums are slow er , and the implementation automatically switches back and forth between them.

You never ask for one of those directly, you will just get one or the other, depending on whether your integer fits into the restricted size of a Fixnum or not.
