DozenCalc 應用程式
A dozenal (duodecimal, or base-twelve) calculator with both simple and scientific modes. Simple mode (automatically chosen when in portrait orientation) contains the four functions, square roots, exponents, and parentheses for grouping, and operates to four digits of fractional accuracy. Scientific mode (automatically chosen when in landscape orientation) has all of the same features, plus trigonometric functions and their inverses, logarithms, reciprocals, buttons for pi and the base of the natural logarithm, and variable precision allowing the user to select the number of fractional digits desired.
