Naming a calculated column in Microsoft Power BI Desktop

Edit the text on the left of the = sign to give your column a name.

Write a formula to add together the values of the Floors above ground and Floors below ground columns and press Enter to complete the calculation.

The column of answers appears at the right hand side of the table.

Create a new calculated column called Average floor height which divides the Height m column by the Floors above ground column. You could do this using the division operator:

Column Name = Value to Divide / Value to Divide By

Or using the DIVIDE function:

Column Name = DIVIDE( Value to Divide, Value to Divide By )

Whichever technique you choose, you should end up with a new column of messy-looking numbers.
