This comment is old but the problem is still there.

The description should state if boolean should be considered as numbers or return None.

At the monent random tests expect None if there is a boolean in the area but very rarely test this kind of array (usually there would also be a letter in the array)

This problem with 19 is still there in the R version.

Hello,

I am doing the kata in R but I encounter some rounding errors with the 0.005.

For example, I round 23.235 to 23.24 but the expected solution is 23.23.

I can't figure out how I am expected to round those numbers:
-R round function doesn't work.
-truncating doesn't work.
-I created a new rounding function in order to always round 0.005 to the next number but it doesn't work either.

What is the rounding rule used in the solution?

@Firefly2002: I don't know JS. But yes, the problem may just be that I am not really familiar with code golfing tricks.

@Unnamed: I like your solution. It is shorter than the others and doesn't use strange syntax.
