InputNumber
Enter a number within certain range with the mouse or keyboard.
When To Use
- When a numeric value needs to be provided.
Types of Supports
sbyte, byte, short, ushort, int, uint, long, ulong, float, double, decimal
Nullable types of the above types are also supported. For example, ushort?, int?, etc.
Examples
Numeric-only input box.
Click the button to toggle between available and disabled states.
Display value within it's situation with formatter, and we usually use parser at the same time.
No border.
value's decimal places is determined by this Precision.
There are three sizes available to a numeric input box. By default, the size is 32px. The two additional sizes are large and small which means 40px and 24px, respectively.
A numeric-only input box whose values can be increased or decreased using a decimal step. The number of decimals (also known as precision) is determined by the step prop.
Supports all numeric types in a generic way, including nullable types.
CultureInfo can be set to ensure proper parsing of strings depending on set locale. Especially useful in ServerSide deployments.
