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

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
