Hey, wait a minute... I used to hear that there were two general classifications of calcs: standard 4 function devices, (because that's what most people used in the good old days, just after the dinosaur extinction), and scientific devices, (which added a memory register and some "advanced" things like square, square root, and basic trig functions, needed to calculate the vast amount of fossil fuel allegedly created by the dinosaur croakage).

To that rather lame definition, and since Excel includes them, Excel IS scientific software. Isn't it?
