Convert field from txt to number

[Robe72]

Hi at all, I'm a new member in this community. I'm training to study DAX language and I'm italian members.
I'm making a little report for my job, I've a database with a 12 columns. I have a columns with a differnt numbers, about from 0 to 8 and I want create a new columns in Manage-Date with a conditions and I done it in this way:

if(dati[delay]>0;"1";"")

Where"dati[delay]" is a logic test.
My problem is that after the result is 1, it is not a number field, but is a txt field. How can I do to change field from txt to number? I tried with "value", but I've an error.
Many thanks for yours answer!
Best Regards

Roberto
