Question about mod function

(0) ShareShare
ReportReport
Posted on by GeekAlf_Pro 402

Hi there,

 

i'm trying to control if an IBAN is correct.

So i transform my input into a number

so far so good.

then i use the mod function to verify my input.

but i feel that i'm out of the range.

what is the limit of the mod in PowerApps ?

Because an example of a number is the following : 

30004015870002601171220152776

here the mod is 0, but if i test by removing the last digit, then the last two then 3 and so on i have always a mod = 0....

 

Thanks

    Hi @GeekAlf_Pro ,

    I had not tested this before, but it seems to be 17 digits - works perfectly up to this then given random (and obviously incorrect) results over.

    Thank you @WarrenBelz 

     

    i found a workaround, by splitting my imput data.

    I calculate the mod of the 12 first numbers.

    then i paste the result in front of the remaining digits

    and calculate again the mod of the new number

    have a good day.
