From the developer:
LiveCalc calculates an expression, while you are typing it. So you can always see the complete expression and you can correct and modify this live and interactive. This works beyond the usual range of numbers.
You may want to check out more software for Mac, such as RAAViewer, Elements or MoonMenu, which might be similar to LiveCalc.
