Smooth movement of slow object

I’m trying to move a bitmap across the screen at a VERY slow pace, but instead of moving slowly, it just seem to move in intermittent stages.

I’m using this code:
spikes.y += .02;

Do objects only move by values that are whole numbers?

Pay attention to the second parameter of Bitmap’s constructor

Try this:

yourBitmap = new Bitmap(Assets.getBitmapData("yourfile.png"), PixelSnapping.NEVER, true);

Perfect! Beautiful movement now. Than you.
