How does the LOG function work in Excel?
The LOG function in Excel computes the logarithm of a number to the base that we specify. It is categorized as a Math/Trigonometry function in Excel. Therefore, the LOG function in Excel always returns a numeric value. For a given number 32, 5 is the exponent to which base 2 has been raised to produce the number 32.
How to do log2 in Excel?
The syntax for using BASE in Excel is =LN(number,base) where number is the number for which you want to calculate the logarithm and base is the base to which the logarithm should be calculated. For example, if you want to calculate the logarithm of 10 to the base 2, you would use the formula =LN(10,2).
Is log in Excel LOG10?
The Excel LOG10 function returns the base 10 logarithm of a number. For example, LOG10(100) returns 2, and LOG10(1000) returns 3.
