WitrynaValue. A vector of the same length as x containing the transformed values. log (0) gives -Inf, and log (x) for negative values of x is NaN. exp (-Inf) is 0. For complex inputs to the log functions, the value is a complex number with imaginary part in the range [ − π, π]: which end of the range is used might be platform-specific. WitrynaNo. The base of the base conversion formula is always 10. The reason for the equation is to allow you to enter a log with a non 10 base into a calculator. The formula is: log base d of c = (log base 10 of c)/(log base 10 of d)
