How to Calculate NDVI Using Landsat 8 Images and QGIS

The NDVI (Normalized Difference Vegetation Index) is a versatile vegetation index to evaluate the vegetation and dynamic of the vegetation coverage change. This index has been studied and evaluated with many satellites over the years, changing its calculus method in relation to the number and type of bands of the satellite. The following tutorial shows the NDVI calculus for Landsat 8 images using QGIS.

great, so nice, but, I would like to get smaller values between -1 or 1, how do I need to do? my equation gives me an actual values big numbers eg. in NDVI for the raw DN values range 7151.5 -21455!
