a=2.65987 ,after using the fprintf('%0.5g\n',a) i get the value i want being 2.6599 i tried doing b=fprintf('%0.5g\n',a) (i wanted to keep a better track of my work ) but it modified my result into 7 ,is there a way of keeping the b=fprintf('%0.5g\n',a) and still keeping the initial value 2.6599 ?

If you want to store the result as ‘b’, use the related function sprintf:
It is a separate line of code, however you get to retain the result.

As always, my pleasure!
In your original fprintf call, ‘b’ was the number of bytes fprintf wrote. See Get Number of Bytes Written to File for an detailed explanation.
