about ruby range?

Question

like this

range = (0..10)

how can I get number like this:

0 5 10 

plus five every time but less than 10

if range = (0..20) then i should get this:

0 5 10 15 20

Answer 1

Try using .step() to go through at a given step.

(0..20).step(5) do |n|
    print n,' '
end

gives...

0 5 10 15 20

As mentioned by dominikh, you can add .to_a on the end to get a storable form of the list of numbers: (0..20).step(5).to_a
