real number, positive or negative. The argument “Number” has a positive numeric
value indicates the number you want to calculate the logarithm. The argument
“Base” is optional, contains a positive numeric value or a reference to a cell
that contains a positive number. Specifies the basis for calculating the
logarithm. If you omit the argument “Base”, the function calculates the
logarithm base 10. For example:
=LOG(5;10) Returns 0,699. Is the logarithm base 10 of 5.
=LOG(5) Returns 0,699. Also calculates the logarithm base 10 of 5.
=LOG(8;3) devuelve 1,893. Is the logarithm base 3 of 8.
