Hello, I notice that in the book the example shown don't define a field type for compute. In that case web2py default seems to create a char var (512) type field. I had no problem with this for storing the computation of decimal result. It also works well if I define a proper field type, in my case decimal... But I would like to know what the best pratice here... Should I set field type or sotre result as string, is it only an oversight when writing the book?
Thanks Richard
