What Hacker News says
7 sources- DC to convert between bases and if you like RPN.
- Calc it's better if you want to cover complex numbers: https://github.com/lcn2/calc
- Qalc from libqalculate in order to solve some equations in legacy machines. It's lighter and smaller than Maxima, but not as complete. - -
- Maxima for anything else, the biggie one. This will cover calculus. Gnuplot will work fine as a plotter for the previous tools.
In Memory-safe, clean implementation of classic Posix "BC" calculatorCalc: C-style arbitrary precision calculator
2 points · Open discussionCode from "The Computational Beauty of Nature" managed to crash CWM under GNU/Linux+X. No issues with FVWM. WIth LibdieHard I managed to avoid the crash.
Maybe some ANSI C code from the 90's doesn't like current layouts...
On FP precision, sh has almost none, AWK often has up to 20 bit and 53 with gawk and the math library. Ditto with bc -l.
Calc has an arbitrary decimal precision and it's really fast.

In How Mandelbrot set images are affected by floating point precisionI like calc paired with gnuplot.

inb4 dc(1)/bc(1)... calc supports complex numbers, C-like pseudo structures/functions, custom decimal points and lots more.
Also, calc/gnuplot will run on a toaster or even legacy systems from 20-25 years ago.
In Desmos 3D graphing calculatorYou need to be very careful, as you may get wrong results due to rounding and floating point errors.
