In FOCUS, how is precision defined?

• A. Max number of digits for values in a column
• B. Max digits after the decimal point
• C. The total number of digits in the table
• D. The number of rows allowed in a column

Answer: (A)

Precision represents the maximum number of digits allowed for values in a column. This sets how large a numeric value can be stored, counting digits on both sides of the decimal point. It’s the total digit capacity of the value, which is why it’s the best match for this concept. Digits after the decimal point are governed by a separate setting called scale, which limits fractional digits. The other ideas—digits after the decimal, total digits in a table, or rows in a column—do not describe precision.
