Is the question whether Raku can somehow understand
You have several useful answers.
I want to summarize what they saButy, and add a couple resources.
* You probably meant 9 ** <1/2>.
Which will display 3.
But it's a Num. It's not the right type if you care about accuracy.
* A solution to get rationals right is built into Raku.

Did you mean the square root of 9 to give 3. Maybe you were wanting cube
root of 27?
Using REPL, I got

Do you expect something else? The result appears to be correct.
Please note that, when dealing with square or cubic roots, Raku will not
use rationals, but ordinary floats.

Hi all,
A quick question.
This is expected?
raku -e 'say 9 ** (1/3)'
2.080083823051904
Why do I'm asking this?
I know about the computational floating problem and I also know that the
Raku deal with rational whenever it is possible and store numbers as
expressions (actually I don't know if the
