=LOG(number, [base])
| Parameter | Deskripsi |
|---|---|
number |
Number for which you want the logarithm. |
base |
[optional] Base of the logarithm. Defaults to 10. |
The logarithm of 16 with base 2 (the power to which 2 must be raised to equal 16) is 4:
=LOG(16, 2) // returns 4
The logarithm of 100 with base 10 (the power to which 10 must be raised to equal 100) is 2:
=LOG(100,10) // returns 2
Because the base argument defaults to 10, the formulas below are equivalent:
=LOG(100,10) // returns 2
=LOG(100) // returns 2
The LOG10 function also returns the base 10 logarithm of a number:
=LOG10(100) // returns 2
=LOG10(1000) // returns 3
