Of course there is, since you can cast the number to a string any time you want, although you'd never need to compute a check digit that's already stored,
Was I casting that integer from its internal format number to decimal, octal or Roman numerals? See the problem?
the point of a check digit being to verify the data before it is used.
Agreed.
No, it's ridiculous to even try to bring Roman numerals into this.
Btw, earlier you lectured:
We do not store computed values in a table
So why are you storing the check digit, since by definition it can be computed??
