logₓy

[cdmackay]

hi all,

I had cause to work out log₂ of a number today, and was vaguely surprised that I couldn't find it on my calculators, not even as a function, let alone on a key. Nor the more general logₓy.

The WP 34S is to be congratulated for having both on keys, but I can't find either even as a function on my DM42 or HP 50g.

It's trivial to write my own fn for e.g LOGy(x) (e.g. LOG SWAP LOG ÷), but am I missing something?
