![]() ![]() Just entering a number is not enough).Ĥ) Click 'ENTER' and you will have your answer.ĮXAMPLE: the base 17 logarithm of 23 is 1.1066918849.Įnter this by clicking logarithm, entering 23 in the logarithm input box, clicking "other" for the number base, entering 17 then clicking "ENTER" and your answer should be 1.1066918849.ĮXAMPLE: The base 6 anti-log of 3.4 is 442.29726239.ģ) Click 'Other' for the number base and enter 6 in the input boxĤ) Click "ENTER: and your answer should be 442.29726239.Īs you probably know, this is the same as saying 6 3.4 = 442.29726239. To use the 'Other' option, click that button and then enter the number base you want. In this case, we can check the powers of 2 to see if we can find the value of x: 2 0 1, 2 1 2, 2 2 4,, 2 7 128, and 2 8 256. The logarithm corresponds to the following equation: log2(256) x. If you don't choose any base, the default is base 10. To find this result, consider the following formula: 2 x 256. That means 10x and log become ex and ln respectively. 2 This is stated as 'log to the base 2 of16 equals 4'. ![]() After you press then the functions will be inverted. With the use of calculators firmly established, logarithmic tables are now rarely used for. On most calculators, this function is denoted by LOG. If the window size is small then just like pocket scientific calculators, secondary options will be put in a state accessible with the Shift key, i.e. You have 4 choices: base 'e', base '10', base '2' and The logarithmic function with base 10 is called the common logarithmic function. For complex inputs to the log functions, the value is a complex number with imaginary part in the range, : which end of the range is used might be platform-specific. log (0) gives -Inf, and log (x) for negative values of x is NaN. (Round your answer to four decimal places.) Evaluate the logarithmic expression. This calculator can compute logs for any number base.Ģ) Enter the number to the right of the "Logarithm of" box.ģ) Select the number base. A vector of the same length as x containing the transformed values. ![]()
