title: Arbitrary Precision Data Types In Java
body: <p>Suppose my architecture supports IEEE 754. This means I'll have 24b for single precision and 53b for double precision. Now supposing in my program, I want to use arbitrary precision - suppose I want precision less than 24b so that my calculations speed up. I don't see anyway I can do this as my hardware does not support it at all. Is it possible to do, say in Java?</p>
  
  <p>If not, then how do embedded computers support these? They are obviously less on the compute power so would want a lower precision.</p>
