For an IBAN Validation, I need to calculate the modulo of a very large number. What I am doing is simply
Example:
with A1 = 210501700012345678131468A1 = 210501700012345678131468
=mod(A1;97)=mod(A1;97)
The result should be 11
. Instead it result in #NUM#NUM
Obviously my value in A1A1
is too large for sheets. How can I "help" sheets?
