How to display a number as $xxx,xxx.xx or even xxxx.xx rather than -4.8e-001

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

Which part of the answers you got on

didn't work out?

Answer 1

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

Majid, you're stubborn.

It's not a matter what out1 IS, but what you see.

out1 is the same as 31356.342, but it's DISPLAYED as 3.135634200000000e+04.

Now you can type in the cmd window format bank, or you can use sprintf to FORMAT the DISPLAY. The number in out1 DOESN'T change.

[Oleg Komarov]

To get it straight, try:

isequal(3.135634200000000e+04,31356.342)
