In the documentation section on formatSpec see the section on Text Before or After Formatting Operators.

r=99
fprintf('%d%%',r)
so when i type this i get 99%. So it's(%%) use is only to print or show percent

[Star Strider]

Yes.

The ‘%’ sign is a format operator for fprintf (and similar functions) so in order to print it as a percent sign, it must be ‘escaped’ by using .'%%'. Similarly, in order to print a ‘\’ it is necessary to ‘escape’ it as well '\\'. See the documentation section I linked to for a full discussion of all of them.
