Chapter 5: Advanced Calculations - Advanced Keyboard 5. TOOL Menu The TOOL menu contains items to help calculating in different number systems, as well as to help solve both linear and polynomial equation. Press @ V to access the TOOL menu. Press the # key (or @ q) to escape from the menu. A NBASE Note: Calculations can be performed in different number base systems, while simultaneously converting the calculation result into hexadecimal, decimal, octal, and binary systems. 1. While this menu item A NBASE is selected, press the E key. The NBASE tool opens, with the cursor set at HEX: (hexadecimal). 2. Type 1B | 9, for example. When entering the hexadecimal B, simply press the B key; using the A key will call up the variable B instead. 3. When done entering the hexadecimal expression, press E. The calculation result will be displayed in three other number base systems, as well as in hexadecimal format. Numerical values in binary, octal, and hexadecimal modes can be expressed in the following number of digits: Binary: 16 digits Octal: 10 digits Hexadecimal: 10 digits If you enter a number exceeding the range specified above for calculations or conversions, the calculator will return an error. If the answer exceeds the above range, the calculator will also return an error. Decimals can be used for DEC mode only (. cannot be used in the other modes). If you convert decimal values to binary, octal, or hexadecimal number, the decimal part is discarded and only the integer part is converted. When numerical values of binary, octal, and hexadecimal modes are negative, the display is switched to complements of 2. 81
