This algorithm requires inputs to go before operators. Example: To raise 4 to 3rd power, press 4 >> Enter, 3 >> Enter, click 'X^Y' button. For more information check with the relevant tool tips if available. Except for Statistics, Matrix, Vector, and Finance modes, Enter key is optional for the last entry. When the input box is empty clicking Enter will duplicate the last entry.
Base Conversions and operations: All integral values can be converted to and from the hexadecimal, decimal, octal and binary bases. All basic mathematic and bitwise operations can be performed in those bases. Except for the base 10, all decimal places are truncated.
Trigonometric operations: All values can be converted to and from the Degree, Radian, and Grads modes. All basic Trigonometric functions can be formed in those bases.
Matrices:
Separate vector elements with a space. Press Enter after each vector or matrix row. For more than one matrix, separate them
with a '/'.
