在 MATLAB Online 中打开

I type in:

fprintf('The final student score is %f\n',round(final_points,1))

and the answer it gives me is:

The final student score is 690.200000

I need this to be shortened to 690.2, but cant figure out how. Please and thank you!

Instead of %f use %.1f

Use the format descriptor: '%.1f' to get one decimal place.

See the documentaion on FormatSpec (link) for a full description of all the options.
