The number 42 is, in The Hitchhikers Guide to the Galaxy by Douglas Adams, " Answer to the Ultimate Question of Life, the Universe, and Everything", calculated by an enormous supercomputer named Deep Thought over a period of 7.5 million years. And the Wikipedia reveals 42 to be important in most religions. Thus Calc is both powerful and worthy of use.
Beyond the sense of humor of the developer, PCalc is my go-to calculator for everything beyond basic arithmetic. It’s also easy and great for basic arithmetic, but it feels like using a Shelby Cobra racing car to go to the grocery store. It is very customizable, and the colors available make the keyboard more readable and usable AND attractive, rather than the “designer” keyboards that blend all the keys together graphically, putting style over function. I like this calculator, and I always have. And I’ve never gotten weird calculation mistakes, like I have with several of the calculators I’ve tried. PCalc is a Keeper.
