The Common and Natural Logarithms - Purplemath Aside: Why would the "natural log" be denoted by "ln", rather than by "nl"? One popular idea relates to Euler ("OY-lur"), the guy who discovered (invented?) the natural exponential. Euler was Swiss and spoke French, so he might have called ...
Binary logarithm - Wikipedia, the free encyclopedia In the analysis of microarray data in bioinformatics, expression rates of genes are often compared by using the binary logarithm of the ratio of expression rates. By using base 2 for the logarithm, a doubled expression rate can be described by a log ratio
Logarithm(log, lg, ln), Logarithmic Formulas - Math Logarithm(log, lg, ln). If b = ac c = logab a, b, c are real numbers and b > 0, a > 0, a ≠ 1 a is called "base" of the logarithm. Example: 23 = 8 => log28 = 3
