Matlab always gives me rounded answers. How do I change it?

I'm trying to use the solve function on my MATLAB but it keeps on outputing answers up to 5 digits only. I would really like to increase the precision of my answers.

I tried using the format function but it's still rounding off. I already have long as my preference in command window>text display>numeric format and variable>format>default array format.

Something in your code has called

digits(4)

You should call digits() passing in the number of digits you want to use.
