Frequently Asked Questions
How do I use the LOG function in Excel?
The LOG function in Excel uses the syntax LOG(number, [base]). The first argument 'number' is required and must be a positive real number. The second argument 'base' is optional and defaults to 10 if omitted.
What are some common examples of using LOG in Excel?
Common examples include: =LOG(100) for base-10 logarithm of 100, =LOG(8,2) for logarithm of 8 to base 2, and =LOG(A2,e) for natural logarithm of value in cell A2.
What are the common errors when using LOG in Excel?
Common errors include #VALUE! when using different data types, #REF! when cell references are invalid, and #NUM! when using invalid numeric values. To avoid these, ensure you're using valid positive numbers and consistent data types.
