For all other values of x, Ln [x, α] returns Log [x]. Log gives the natural logarithm (to base ): Series expansion shifted from the origin: Asymptotic expansion at a singular point: The precision of the output tracks the precision of the input: Evaluate Log efficiently at high precision: Log threads elementwise over lists and matrices: It threads over lists in either argument: Simple exact values are generated automatically: Find a value of x for which the Log[x]=0.5: Log is defined for all real positive values: Log has a branch cut along the negative real axis: Derivative of a nested logarithmic function: Plot the first three approximations for Log around : General term in the series expansion of Log around : The first term in the Fourier series of Log: Logarithm of a power function simplification: Log arises from the power function in a limit: Log can be represented in terms of MeijerG: Log can be represented as a DifferentialRoot: Log can deal with real‐valued intervals from : Plot the real and imaginary parts of Log: Plot the real and imaginary parts over the complex plane: Plot data logarithmically and doubly logarithmically: Benford's law predicts that the probability of the first digit is in many sequences: Analyze the first digits of the following sequence: Use Tally to count occurrences of each digit: Shannon entropy for a set of probabilities: Exponential divergence of two nearby trajectories for a quadratic map: Compositions with the inverse function might need PowerExpand: Get expansion that is correct for all complex arguments: Convert inverse trigonometric and hyperbolic functions into logarithms: Numerically find a root of a transcendental equation: The natural logarithms of integers are transcendental: Log is automatically returned as a special case for various special functions: For a symbolic base, the base b log evaluates to a quotient of logarithms: Because intermediate results can be complex, approximate zeros can appear: Machine-precision inputs can give numerically wrong answers on branch cuts: Use arbitrary‐precision arithmetic to obtain correct results: Compositions of logarithms can give functions that are zero almost everywhere: This function is a differential-algebraic constant: Logarithmic branch cuts can occur without their corresponding branch point: The argument of the logarithm never vanishes: But it can take negative values, so the logarithm has a branch cut: The kink at marks the appearance of the second sheet: Logarithmic terms in Puiseux series are considered coefficients inside SeriesData: In traditional form, parentheses are needed around the argument: Successive integrals of the log function: Calculate Log through an analytically continued summed Taylor series: Visualize how the value is approached as : Log10  Log2  Exp  Power  Arg  RealExponent  MantissaExponent  ProductLog  HarmonicNumber  MultiplicativeOrder  BitLength  IntegerLength  LogPlot  PowerRange.
