If you want to do it without using strings:
round(x * 100) / 100;
One reason you might want to do that is if you have a whole matrix of percentages and want to quickly show them in a sensible way, without messing with the output format for other numbers.

Example:
x = 0.78765645; % almost 78.8%
sprintf('%0.2f',x)
ans =
0.79
Is this the effect you're trying to accomplish?

By the way, the 0 is not necessary. I always just use sprintf('%.2f',x)
