number of floors as a float?

[KFSchlager]

Hello,

I have data of buildings with exact GFA and would like CEA to use this for the calculation.

Am I correct that CEA calculates the GFA using the number of floors multiplied by the area of the shape file from OSM?
So the only way to get the correct GFA would be to divide the GFA by the area of the shape file and then enter the resulting number of floors as a float.

Is there a way to enter the number of floors as float or another solution? Thanks in advance!
