Raster Calculator

Hello!
I try to calculate NDVI using Raster Calculator:

But result has only three values (and three colors): -1, 0 and +1.
What am I doing wrong?
Thanks!

This is a feature of Python 2.x. When you divide two integers, you will will get integer output:

>>> 1 / 2
0
>>> 1 / 2.0
0.5
>>> float(1) / 2
0.5
