Yeah, that should be fine. So what are you getting in return? And what values are you actually sending to toString?

I tried this : var test = toString(integer, numerator, denominator); but i'm not sure this is correct.

It returns a string, which you can then log out if you wish. Take an example that you're trying to use toString for. What arguments are you sending to it?

Cool

Thanks for this kata, was not so easy to solve but it learned me a lot. I couldn't use the toString function and i don't know exactly why? Is it something we must code?

Yeah thanks.

Ah--sorry about that. Does it work okay for you now?

Hello,

Nice Kata but in tests i have a weird return :

"(xx/xx) should simplify to (x/x), but simplified to "

There's no indication of what my feature returned.

@brice: In which comment do you want to add a (which?) message ?

Just formal issue : Add a message in comment. Great Kata.
