Question

I have this simple question actually but I can’t find the correct answer.
I would like to know how i could do something like this:

    direction="-"
    value=17
    movement = direction value

so that it would give me: movement=-17
I know i could use an if statement but I was wordering if there is a quicker way for converting “-” to simply –

Answer 1

One solution from my side

direction = "-"
value = 17
movement = (direction + value.to_s).to_i

It is very basic, not using anything complex, which might make it a bit unclean, but at least demonstrates that knowing just the very basic operations in ruby you can solve many tasks.
