There is likely a more elegant solution, but with copy paste, brute force will works. Fortunately, the Ancients created a number system with only 10 digits.

The 10 digit number system notation development is credited to two great mathematicians from ancient India,

**Aryabhat** (5th century BC) and

**Brahmagupta** (6th century BC).

The second dude in 6th century BC invented the zero.

Had the

Mayan system taken hold the formula would have needed to be twice as long as they had 20 digits. Must have been bad for business as they are not around any more.

But here is a formula for the Base 10 system.

Contains([my field],"0")

or

Contains([my field],"1")

or

Contains([my field],"2")

or

etc

....

Contains([my field],"9")
