# Numeric input

A numeric input interaction item is used when the operator is required to supply numeric information, either manually (using a keyboard) or with the aid of a barcode scanner. Numeric inputs treat both points (.) and commas (,) as decimal separators.

Numeric inputs have the following properties:

* **Target Variable**\
  The name of the new variable in which to store the number entered.
* **Prompt**\
  The label to be displayed over the numeric input field.
* **Default Value**\
  The number that will be entered as default when the operator first enters the user task.
* **Condition To Hide**

  Add the condition that must be met for the control to be hidden. If left empty, the control will be visible in the user step. Note that when controls are hidden, empty variables will be created, unless default values or pre-defined data exist.
* **Allow Empty Input**\
  If set to **True**, the operator is allowed to move forward in the workflow without entering anything into the numeric field.
* **Merge behavior**

  The control behavior at reloading, see [User step reloading](/development/flow-studio/applications/workflow/user-step.md#user-step-reloading).
