For my code I'm required to have an absolute error below 1*10^-6 when I get MATLAB to display the error it's so small that it just shows up as 0.000000. I want to make it display more numbers after the decimal point but I don't know where exactly I need to be typing the commands. Any help would be appreciated :)
i
root=(w_left+w_right)/2;
absoluteerror=(w_right-w_left)/2;
fprintf('The estimated root is %f \n',root)
fprintf('The absolute error is %f \n',absoluteerror)
if absoluteerror > (1*(10^-6))
disp ("Absolute Error is too large! Try increasing number of bisections to be used")
else
disp ("Absolute Error is sufficiantly small")
end

fprintf('%.16e',pi)
values = sprintf('%.16e %.2g %f %.2f', pi*50*ones(1,4))
