Converting an integer to a hexadecimal string in Ruby
Is there a built in way to convert an integer in Ruby into its hexadecimal equivalent? Something like the opposite of String#to_i: “0A”.to_i(16) #=>10 Like perhaps: “0A”.hex #=>10 I know how to roll my own, but it’s probably more efficient to use a built in Ruby function. 5 Answers 5
