Yes, anyone can make a calculator. I don't care if it gives me "Underflow" for bs like e^-1000, just give me a text field that will be calculated into result that's represented in the way I want (sci notation, hex, binary, ascii etc whatever). All standard calculators are imitations of a desktop calculator, It's insane that we're still dragging this UI into desktop. Why don't we use rotary dial on mobile phones then? It's great that at least OSX have cmd+space where I can type an expression and get a quick result. And yes, I did develop my own calculator, and happily used it for many years. TLDR: the real problem of calculators is their UI, not arithmetic core.
