title: Datatypes for physics
body: <p>I'm currently designing a program that will involve some physics (nothing too fancy, a few balls crashing to each other)</p>
  
  <p>What's the most exact datatype I can use to represent position (without a feeling of discrete jumps) in c#?</p>
  
  <p>Also, what's the smallest ammount of time I can get between t and t+1? One tick?</p>
  
  <p>EDIT: Clarifying: What is the smallest unit of time in C#? <code>[TimeSpan].Tick</code>?</p>
