Number

A numeric input field with min, max, and step constraints.

Overview

The Number field renders an input[type=number] element that restricts input to numeric values. It supports integer and decimal values, configurable min/max bounds, and a step increment. Browser-native number spinners are shown.

For visual range selection (sliders), use the Range / Slider field instead. For calculated numeric values derived from other fields, use the Calculated Field.
