What about calc (currently in the package of that name, formerly in the package apcalc)? That being what I've used for over a decade now. Reading through the bc man page, it looks to me as if using calc it should take comparable numbers of keystrokes, aside from typing the name of the program itself. In some contexts it could even need fewer; for example, calc (as shipped in Debian) provides the built-in function 'pi()', which takes a precision - expressed as a value between zero and one - and returns pi to that level of precision. The list of built-in functions in the bc man page is very short, and doesn't include any such thing, so unless something has added one without the man page getting updated anything that needs to use pi is going to take more typing than with calc. calc also has the option to present non-integer output in the form of a ratio of two integers, which means you don't have to figure out manually what fraction a given result is; at a skim, I don't see indication that bc has comparable functionality. I've heard recommendation of bc before, but to date I've yet to encounter anything that makes it seem preferable over calc, and I'm curious what I'm missing. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
