SpeedCrunch is a fast, high precision and powerful desktop calculator.
SpeedCrunch is easy to use. You just type the expression that you want to calculate and press Enter. You can see clearly what you typed along with the result in the scrollable display. That is faster and more convenient, isn’t it?
You can also paste the expression from the clipboard, that you copied from somewhere else. And, you can quickly copy the last calculation result to the clipboard using Ctrl+R.
Before you finish, SpeedCrunch may even give already the answer (calc-as-you-type)
