采纳的回答： Jan

I have a disp command that returns the status

num2str(total,'%i')

For some reason it is returning the totals as

-4.808337e-001

How can I have it return smply as .048 or .04?

Most of the amounts are currenty so ideally formatted $xxx,xxx.xx would be perfect

在 MATLAB Online 中打开

sprintf('%.2f', -4.808337e-001)
>> -0.48

I do not see a sufficient and reliable method to display this as ".048" or ".04". Do you really want to omit the leading sign and zeros and divide the fractional part by 10?

hi dear i have approximately same this problem look at this code

n = 3456;

% Separate them

na = num2str(n) - '0';

% substitute the 4 (position 2) with 13

na(2) = 13;

% Recombine

out = str2double(sprintf('%d',na)); %out will be 31356 but double

out1 = out + .342; % out1 will be 3.135634200000000e+04 but double

out2=sprintf('%.3f',out1); %out2 will be 31356.342 but character

but I want 31356.342 but double

thank you dear
