Test criteria is wrong, can't assert the right return value.

The description has been updated to state the precision of the conversion factor used in the test suite.

Problem statement needs to be updated to state precision of submitted values. Only accepts values rounded to 4-decimal places.

Answers need to be rounded to 4 decimal places

If you're facing the issue where your code is producing correct results, but the assertion tests fail, use the round() function and set the precision to 4 decimal places.

% my solution - print out y value to compare against y_correct
y = x / 2.205;
disp(['y = ' num2str(y)])
disp(y)
% Test 2 and 3 Fail....
x = 50;
y_correct = 22.6757;
assert(isequal(convert_stuff(x),y_correct)) % Assertion failed.
Output:
y = 22.6757 % NOT SURE WHY THIS FAILS????
22.6757
%% Does not look like a precision issue
