Automatic scientific notation in TH2 text plot

I’m trying to figure out how to control the formatting on the numbers generated using TH2D::Draw(“text”). When the value of the individual cell goes to 1,000,000 the text switches to scientific notation. I would like to control that change and control the number of significant figures when it does change. Any guidance?

See attached screen shot for example.

Thanks,
Chris
