... Logarithms based on the number e are called natural, or base e,logarithms (abbreviated ln). The natural log of a number is the power to which e (which has the value 2.71828 ... ) must be raised to equal the number. For example, the naturallog of 10 equals 2.303. e2·303 = 10, therefore ln 10 = 2.303 ...
