Hi, (01-12-2019 09:09 PM)cdmackay Wrote: 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 HP-71B has several log functions (some in the mainframe and some in various ROMs), including LOG2(X) which admittedly is very handy for all sort of programming tasks. I also think that the HP-75 had a general Log to any base, not sure if in the mainframa or perhaps in some ROM or other. V. All My Articles & other Materials here: Valentin Albillo's HP Collection |
