MATLAB round values such that none are zero

I have an array of values and I am trying to round them all to integers, but I don't want any of them to become zeros.

Some of the values look like this:

0.00001
-0.03
-0.000001
0.789
1

I would like the result after the rounding to look like this:

1
-1
-1
1
1

I tried round(), ceil(), floor(), etc. but I'm not sure what to do in this case. Any advice?
