Why is `27 ** (1.0/3.0)` different from `27 ** (1/3)`?

ruby

Solution

1.0 / 3.0 # => 0.3333333333333333
27 ** 0.333 # => 2.9967059728946346

1 / 3 # => 0
27 ** 0 # => 1

The second is an example of integer division. How many threes are there in one? Zero. Any number in power 0 is 1.

Problem

Please let me know if this is correct way to get the cubic root. I can't understand why ``` 27 ** (1.0/3.0) #=> 3 ``` is different from ``` 27 ** (1/3) #=> 1 ```
