In ruby 2.3 they are changed.

Kanna, this is not true, in Ruby 2.3 the strings are not immutable by default. This is going to happen in Ruby 3. However, it is possible to make strings immutable in Ruby 2.3 if you use the frozen_string_literal: true pragma or start Ruby with the –enable-frozen-string-literal option. Then you could do strings formatting with String.new "Some %0.2f" % 78.938 and the output will be Some 78.94.
