fail for x=120?! 'isequal(factorial(120),y)' gives me 0...

My solution works in Matlab, but fails the last test here.. :(

I am trying to solve this problem and first 2 test cases are passed, but assertion is failing for last test case. I also used the format as 'short eng', here the y_correct is read by Matlab as '6.689500000000000e+198', but my program is calculating answer as '6.689502913449124e+198' for x = 120 and thats why its failing. Any suggestions ?

There is something wrong with the last test; The number are truncated. y_correct should be 6.689502913449135e+198; while in the test it is given as 6.689500000000000e+198

fake solution, it works until there is a mistake in test 4

I KNOW THIS SOLUTION IS CORRECT....STUPID IDE IS NOT ACCEPTING IT....YOU CAN RUN IT ON A STANDALONE MATLAB AND SEE IF IT WORKS!

Nice solution for that rounding problem.

There should be a test in the test suite to catch any uses of "factorial" in the submitted code, as is done here:

Also, is the convention here to round to five significant digits? If so, this should probably be noted in the problem statement.
