How can I avoid frequent int / float / double operations when developing an XNA application?

Question

I am making a simple 2D game for Windows Phone 7 (Mango) using the XNA Framework.

I made the following comments:

• Most drawing operations accept floats
• SpriteBatch.Drawaccepts Rectanglethat uses ints
• The class Mathtakes doubleas parameters, and also returns doubles

So my code is full of types with ints, floatand doubles. This is a hell of a lot of types.

Is there a way to get rid of them, or do I just not need to do this?

In addition, do these drives exist in the form of measurable performance losses?
