They are methods in the Kernel module. Method names with a capital 
initial are unusual, but allowed.

irb(main):005:0> Kernel.methods.grep(/^[A-Z]/)
=> ["Array", "Integer", "Float", "String"]
irb(main):006:0> Integer("123")
=> 123
irb(main):007:0> Integer("0123")
=> 83
irb(main):008:0> Integer("0x123")
=> 291
