Force Convertion of String to Number using Dax

[NPbon]

Hello everyone,

I have a column that was created with DAX (hence cannot use power query) as a Text that needs to be converted to Number.

However, sometimes on this column there are non-numerical, non-roman characters as the source is taken from multiple languages around the world. 

When using CONVERT function, if only in one of the rows there is a special character, all rows are changed to  #Error.

I want to know if there is a function that forces the convertion (omitting or deleting the special character) or at least that changes to #Error only the row with the problem, and not the entire column. 

Many thanks,

[NPbon]

Hello,
The solution provided Did not work for the intended purpose at all.

When using it I got an error: "Expressions that yield variant data-type cannot be used to define calculated columns".

An Example of my problem, and how I would like the solution (using 0.04 as error code)
14.45  --> 14.45
14#  --> 0.04
103 --> 103
$18 --> 0.04

when trying to use 0.04 instead of "Not number", all rows became 0.04

Any other idea with this?

Hi @NPbon ,

Plese try to identify the column firstly, then convert the data type, please try to create a column like below dax formula:

Column =
VAR cur_val = [Column Name]
VAR _a =
    SWITCH (
        TRUE (),
        ISNUMBER ( cur_val ), CONVERT ( cur_val, INTEGER ),
        ISNONTEXT ( cur_val ), CONVERT ( cur_val, INTEGER ),
        "Not number"
    )
RETURN
    _a
