I wanted to chime in as a calculator dev dude. Qalculate is really nice if you want the kitchen sink, which I do on the desktop. I also, depending on the task use speedcruch which others have mentioned. Using https://github.com/ArashPartow/exprtk https://github.com/ArashPartow/exprtk I have one calculator with a repl at 512kb, including a QML wrapper. I have a combined rpn calculator using sympy (based on the work of others) with exprtk as a 'programmer's calculator' on the side (https://github.com/poetaster/fibonacci https://github.com/poetaster/fibonacci). And several QML apps for symbolic CAS using sympy. I have way too many calculators. They are so much fun to build. Now I ask myself, port the Qalculate methods to macros for exprtk or check out using libqalculate? I'm not sure. exprtk is so light? And adding macros discrete.
