format long g

and then display the number

Thank you, that works pretty well. One more question, please, how can I do if I want to show like that using "fprintf"

@Quynh tran: you can read the fprintf documentation and you will learn to how to use fprintf. The output of fprintf depends on the format string, which depends on what the inputs are, and the desired output, which you told us nothing about. So, do some experiments with it in your command window: the more your practice them more you will learn.
