CCCalc combines the simplicity of desktop calculators with the power of spreadsheet applications. It performs four basic arithmetic operations and percents too. CCCalc has no limitations on precision and allows you to control rounding up as desired. CCCalc automatically remembers everything you've entered until you delete it yourself. It allows you to browse through the calculation history as if it were a text and reuse numbers or correct any misprint at any moment, the result will be recalculated automatically.
