Log Function (BASIC)

+Returns the natural logarithm of a number. +

+ +Log (Number) + + +

+Double + +

+ Number: Any numeric expression that you want to calculate the natural logarithm for. +The natural logarithm is the logarithm to the base e. Base e is a constant with an approximate value of 2.718282... +You can calculate logarithms to any base (n) for any number (x) by dividing the natural logarithm of x by the natural logarithm of n, as follows: +Log_n(x) = Log(x) / Log(n) +
