I didn't know "roundn". Thanks.

Ilias Patelakis on 16 Jul 2017

My solution is correct BUT the test cases result in error due to the roundn() function.

Pablo Lobo on 26 Aug 2017

Please solve the situation with the test cases. Same issues as the other people commenting. Problems with roundn.

Please update the tests to deal with the "roundn" issue.

I thought roundn may have been replaced in the latest version of MATLAB, but it seems to still be present in 2017a. Any idea why it's not working in the Cody interpreter?

There is a bug in the tests.

Please fix the issue of roundn

the matlab2017b does have the " roundn" function ,
all the functions are combined with the "round" function .

The tests have bugs in them. Please correct them as soon as possible.

Fix the issue of roundn. The test cases are not working.

The roundn function is not recognized. The test cases are not working.

This test has a problem with roundn function. I have also tried to use elseif and insert the exact values of s, but it doesn't work.

Srishti Saha on 8 Aug 2018
