patch 9.0.2114: overflow detection not accurate when adding digitsv9.0.2114
Problem: overflow detection not accurate when adding digits
Solution: Use a helper function
Use a helper function to better detect overflows before adding integer
digits to a long or an integer variable respectively. Signal the
overflow to the caller function.
