Casting (float) everywhere in C#. Is it better to just work in doubles?

Question

Working on an XNA game, I'm using float for most of my number values. Most C# functions seem to input/output doubles so I'm writing (float) a lot. Should I just be using Doubles or is how I'm working OK?

Answer 1

You should be using doubles. They are more accurate than single precision floats and there will be an overhead for casting.
