I can't get my function to work or print right

x=(0:31);
y=(2.^x);
disp(y)

Im just trying to get a list of values from 2^0 to 2^31. I know the range is right but I guess theres something I don't understand about functions because the values are mostly below 1.

The values are not below 1: you have been fooled by the way the default output format

x=(0:31);
y=(2.^x);

disp(y)
