arpra VS calc

I don't know why everyone else is talking about bignums, but this is a fairly common subject of interest with lots of research projects out there. Off the top of my head Arpra, and CADNA. Julia also has IntervalArithmetic.jl which can be used with some manual work. None of these are core language features, but I don't imagine that was an important part of the question.

http://www.isthe.com/chongo/tech/comp/calc/index.html not sure why you chose exactly the same name as the original calc. Even if you plan to create a drop in replacement. It's not good practise to use exactly the same name than another active project in the same problem domain

my benchmarks againts qalc and c-calc shows that c-calc takes about 0.8ms mean to run a calculation,qalc takes about 96.4ms to run a calculation,and mine takes 0.5ms to run a calculation, of course this is pretty much just the startup time however i cant measure the runtime speed againts c-calc because it does not allow multiple arguments like mine does.

I like calc myself, works quite well. Doesn't have e preloaded as a constant, to my knowledge at least, but otherwise it is very good.

calc: a command line calculator with arbitrary precision. GNU bc is good too, but calc has more built-in commands (combinatorial, number theory functions for example). You can use it interactively, or simply to provide the results of a calculation. Try this: in your terminal, enter

There's also another calc: https://github.com/lcn2/calc
