Is there a 64 bit version of Rails?

Hello, I'm new here and I'm looking at using Rails for web development.
Is there a 64 bit version of Rails or does one version run on 32 bit and
64 bit platforms. by the way, I did a search on this subject and was
unable to find any information.

Thanks for the help!

Rails is pure Ruby. There's no such thing as a 32-bit vs 64-bit
version of Rails.
