Strange error n NORM.S.INV function DAX when creating a column.
I'm trying to add a calculated column in Power BI modeler with DAX. In a column X I have a probability, say 0.08 or 0.01 For that column X I'd like to add the calculation of NORM.S.INV(mytable[columnX]) I get an error: An argument of function 'NORM.S.INV' has the wrong data type or the result is too large.
Datatype is okay, though.
When I enter NORM.S.INV(0.08) or some other value of column X this works fine. Same table in Excel with this function works fine as well.
The same issue occurs with a measure. As soon as it has only a single value, it returns the same error.

The only thing one can say is... make sure the data type of the column is correct. Also, since the normal distribution has a support which is the whole real line, for some values the number returned from the inverse of the distribution function can be too large, indeed.
