Right, ok.
So in my example, I have Bitmaps being drawn to the Canvas (using an
adaptation of SpriteMethodTest which I referred to a few days ago).
1) The Canvas.drawBitmap() method takes two floats as coordinates, so
how can I avoid using them? Or if i was to pass 'integer' values,
would that
What you are searching for is called fixed point math. The reason to
do this on Android is that many current devices don't have a floating
point processing unit. This will change in future devices i'm sure
(all second generation devices seem to have an FPU).
If you work in Java it does not pay of
First: what you are in need off is called fixed point math which is
implemented by using integers, deciding how many low bits to use for
the fractional part of a number and then do some shift magic to do
basic math operations. It's an old trick used mainly on devices that
do not have an FPU like
I've done numerous testing on this issue when I was coding my audio
apps.
Using fixed point in the Java code gains NO benefit at all.
Using fixed point in NDK native code gives you a MASSIVE speed boost.
Like 2 to 4 times faster.

Interesting, thanks.
To go back to my other question, can some one confirm this:
When bitmaps get drawn to the screen, is this all wasted
precision? Is drawing at 281.01068 any different from drawing at
281.31343?
i.e. does it just get drawn at point x=281?

I would say - Yes.
