GNU Octave, round a number to units precision

In GNU Octave version 3.4.3 I want to round a matrix to 2 units precision on the contents of a matrix like this.

mymatrix=[1.1234567, 2.12345; 3.1234567891, 4.1234];
disp(mymatrix);

This prints:

1.1235   2.1235
3.1235   4.1234

As you can see, the disp forces the precision to '5', I want the units precision to be 2. How do I do this?
