Solution 15320: Performing Order of Magnitude on the TI-86 Graphing Calculator.
How do I perform an order of magnitude computation on the TI-86 graphing calculator?
The order of magnitude of a number is the number of powers of 10 contained in the number. Generally, the order of magnitude of a number can be defined in terms of the decimal logarithm, usually as the integer part of the logarithm.For example, 4,000,000 has a logarithm of 6.602. Its order of magnitude is 6.To find the decimal logarithm (or log) of a number:
• Press [LOG], input the value and press [ENTER]
The antilog of the log is 10 raised to the power of that number. For example, the antilog of 2 is 10^2. This function is accessed by pressing [2nd] [LOG].
Please see the TI-86 guidebook for additional information.
