Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

what is the return type of sqrt function.Isn't it double? or it depends upon the type of argument passed.
If is is double thn why IDE's only print int if the number is a perfect no.
ex. sqrt(9) : 3 Why not 3.000000000000000 or 3.0 ?
