<br />
At first I tried using an addition without assignment (ie num1 + num2) but this didn't seem to do anything, so I included an assignment (ie result = num1 + num2) and included a constant assignment in the "empty" for loop.<br />
<br />
<br />
Here is a description of what my code does.<br />
All repetitions are achieved using for loops.<br />
<br />
(1) Perform an assignment n times<br />
<br />
(2) Perform an addition (including assignment) n times<br />
<br />
(3) Subtract time taken for (1) from the time taken for (2)<br />
<br />
(4) Repeat this five times and take an average<br />
<br />
== Results ==<br />
<br />
These are just one set of results. In total, I had many varied results.<br />
All times are for a single addition in nanoseconds.<br />
<br />
<br />

== Thoughts ==<br />
<br />
It seems that all the types perform addition in about the same time. Why? It might be because I only added small values.<br />
<br />
The exception to this is type short. This type seemed to take significantly longer. Why?</div>Mark
