Change variable precision used

Hi

IDK how I made this to my MATLAB, but it has changed to using only 4 precision digits, how can I fix it to its default which I think might be 32?

for example I get the following answers for these codes:

>>round(pi,9)

ans =

3.1416

>>round(0.55555,3)

ans =

0.5560

format long

or

format long g

You can also control the default that you get on startup, by going into Preferences
