Hi all,
I have a question about the scientific notation.
I wrote a program and i obtained the result a number like this:
now I want to put on the graphics and I wrote:
TPaveText *pt = new TPaveText(0.15,0.7,0.30,0.85,"brNDC");
char text1[100];
sprintf(text1,"k = %f", max_k);
char text2[100];
sprintf(text2,"#sigma = %f", sigma);
pt->AddText(text1);
pt->AddText(text2);
pt->Draw();
but I obtain only zero: 0.00000
Do you have any ideas?
Thank you
Ciccio
