Natural Logarithm, Natural Antilogarithm

Page 11 highlights

To calculate a root: 1. Enter the number (y) whose root you want to find. 2. Press 0 H. 3. Enter the root (x). 4. Press 0 \. 5. Press l or any key that completes the operation. 0 G (Natural Logarithm)-Calculates the natural logarithm (base e = 2.718281828459) of the displayed number. The number must be positive; otherwise, an error condition occurs. 0 ^ (Natural Antilogarithm)- Calculates the natural antilogarithm of the displayed number. This is equivalent to the value of e raised to the power of the number in the display. 11
