Thread Subject: fprintf - get rid of exponential -

Hi all!!

I'm writing some numbers into a file. I want to write them without any dots(.) or exponentials(e) but I can't.

i.e. I use the command

 fprintf (truefile,'%8d\n',true);

to write the number '80539' to file. but in file I see '8.053900e+004'.

how can I get rid of these (.) and (e)?

Thanks in advance...

Hi!

>>help format

That should do the trick. Change the format of numbers.

Hope this helps you !

Best regards,

Michael

thanks for your reply Michael.

I read each line of 'format' and 'fprintf' help pages but I couldn't find a solution to my problem.

do you think that there is an alternative way??

As far as I know you should use format short to have 5 decimals so type in command window :

>>format short

Then I'm not sure if I'm saying right you should eliminate the decimals for your number using a dedicated function in matlab:

Here's the link:

If you're done please tell me how you remove the decimals from a number I don't have matlab at my means to test this!

Thanks and waiting for your reply!


Just an idea!

So you want to round a number:

In this case you can use:

>>a=31.19453

>>rounded_result = roundn(31.19453,-1)
>>roundeed_result

and this is the answer. thanks for your help Michael.
