This little calculator supports basic arithmetic operations, trigonometric and logarithmic functions, binary, octal and hexadecimal calculations and comes along with 40 constants. Most features are self-explanatory as the calculator works pretty similar as a usual calculator.
You can find a more detailed description of supplied functions and terms of use on the developer website.
