Double factorial [wp34s]

True – but this applies other constants as well. Some physical constants provided by the 34s are simply products or quotients of two others. Or consider cases like Φ₀ and K_j – the one is simply the reciprocal of the other, so at least one of them is not required. And what about #eE? A simple 1 e^x would be fine either, wouldn't it? Even without disturbing the stack like a manual [pi] 2 [/] would do.

OK, constants like ln 2 or lg e can be obtained with two program steps, and they don't even cause stack problems (well, except losing LastX). Others do, so I would trade several of the present physical constants for a simple pi/2, pi/4 or some others.

But you said that the assembler can handle several constants, I assume this applies to cases like ln 10 or sqrt(2 pi). Could you kindly provide a list of these?
