The Number Field

The Number field restricts data entry exclusively to numeric values, ensuring that the captured information can be processed or validated mathematically.

Name:

Behavior in the interface

• On the frontend, the field usually shows increment/decrement controls (arrows) and prevents typing alphabetic characters.
• The stored value will strictly be of numeric type (Number) in the database, which facilitates search, sorting, and aggregation operations in the system.
