Table calculation (division) is showing a wrong result

[cgerauy]

Hi Looker team,

I’ve set up a metric in Looker Studio called ROI = (x - y) / y

The result is wrong, i.e. In the image in the first row should be = 0.0527 instead o 7,33

Furthermore, the result of 1/y it´s also wrong but y/100 gives the right answer.

Could somebody help me?

Thanks in advance.
