The logarithm keys (log for base-10 and ln for base-e) on a typical scientific calculator. The advent of hand-held calculators largely eliminated the use of common logarithms as an aid to computation. The numerical value for logarithm to the base 10 can be calculated with the following identities: [5]
In mathematics, the logarithm of a number is the exponent by which another fixed value, the base, must be raised to produce that number.For example, the logarithm of 1000 to base 10 is 3, because 1000 is 10 to the 3 rd power: 1000 = 10 3 = 10 × 10 × 10.
To get the base-10 logarithm, we would multiply 32,582,657 by log 10 (2), ... A single valued version, called the principal value of the logarithm, ...
Equally spaced values on a logarithmic scale have exponents that increment uniformly. Examples of equally spaced values are 10, 100, 1000, 10000, and 100000 (i.e., 10 1, 10 2, 10 3, 10 4, 10 5) and 2, 4, 8, 16, and 32 (i.e., 2 1, 2 2, 2 3, 2 4, 2 5). Exponential growth curves are often depicted on a logarithmic scale graph.
When the reference value is 10, the order of magnitude can be understood as the number of digits minus one in the base-10 representation of the value. Similarly, if the reference value is one of some powers of 2 since computers store data in a binary format, the magnitude can be understood in terms of the amount of computer memory needed to ...
It may also refer to the binary (base 2) logarithm in the context of computer science, particularly in the context of time complexity. Generally, the notation for the logarithm to base b of a number x is shown as log b x. So the log of 8 to the base 2 would be log 2 8 = 3.

Four powers of 10 spanning a range of three decades: 1, 10, 100, 1000 (10 0, 10 1, 10 2, 10 3) Four grids spanning three decades of resolution: One thousand 0.001s, one-hundred 0.01s, ten 0.1s, one 1. One decade (symbol dec [1]) is a unit for measuring ratios on a logarithmic scale, with one decade corresponding to a ratio of 10 between two ...
