logₓy
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? Cambridge, UK 41CL/DM41X 12/15C/16C DM15/16 17B/II/II+ 28S 42S/DM42 32SII 48GX 50g 35s WP34S PrimeG2 WP43S/pilot Casio, Rockwell 18R |
