How to print percent sign in TPaveText?

Hi,

I would like to have s_G = x.x % printed in TPaveText,
but I cannot figure out how to get the percent sign in the end.
I have something like
TPaveText pt(.55,.6,.98,.8, “NDC”);
TText t1=pt.AddText(Form("#sigma_{G} = %g ", 100fit->GetParameter(2)));

What should I add to get the percent sign?

                    Best regards,

                                  Kati

TText t1=pt.AddText(Form("#sigma_{G} = %g %%",100fit->GetParameter(2)));
