Rmatrix VS calc

Nevertheless, if you need to add matrices, you can have a look at my little library I wrote as a starting point. https://github.com/NJdevPro/Rmatrix I am a Rust beginner, so it may not be very rusty (it's literally the first and only Rust code I've written so far), but it's simple enough.

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
