To use the LOG10 function in Power BI DAX, follow these steps:
Step 1: Enter the Function
To use the LOG10 function, you need to enter it into a DAX formula. The general syntax for the LOG10 function is as follows:
Here, "Number" is the value that you want to calculate the logarithm of.
Step 2: Add the Number Argument
Once you have entered the function, you need to add the number argument. This is the value that you want to calculate the logarithm of. For example:
This will calculate the logarithm of 100 with a base 10.
Step 3: Use the Result
Once you have entered the function and added the number argument, the LOG10 function will return the result. You can then use this result in your calculations and visualizations.
Let's say you have a table in Power BI that contains sales data for your company, and you want to calculate the logarithm of the total sales for each month. You can use the LOG10 function to do this as follows:
This will calculate the logarithm of the total sales for each month with a base 10.
