My little discoveries were much less exciting, but interesting nonetheless. I'm sure they're well known, but it was fun discovering them myself anyhow:
<ul>
<li>Extra digits: In order to calculate long decimal values, the calculator stores 2 extra digits beyond what you can see on the screen. This means after a few calculations involving decimals, you may eventually see just the value 3 displaying, but the calculator is actually storing 3.00000000001, so subtracting 3 from what appears to be 3 will give you 0.00000000001 and not 0 as expected.</li>
<li>y<sup>x</sup> uses an algorithim and not straight multiplication: I discovered the extra digits above by experimenting with this. If you try 2<sup>3</sup> using the y<sup>x</sup> function, 8 will correctly appear. But, if you subtract 8, you'll get 1<sup>-11</sup>. This is because exponential numbers take considerable calculation and instead an algorithim is used. This isn't noticable on higher numbers, but on low numbers the difference can be seen.</li>
</ul>
