In Ruby on Rails, Dig refers to a method used for navigating through nested hashes. It can be used recursively to access values in multi-level hashes. Float is a built-in class that represents floating point numbers. Max is a method used to find the maximum value of an array or range. For example: dig({a: {b: [1, 2, 3]}}) # returns 3, float(2.5) returns 2.5, and [1, 2, 3].max # returns 3.
