Number Input {#example_number_input}

Simple keyboard that limits user inputs to a full number (integer). Useful to enforce correct entries without the need for intense validations after a user input.

General principle

Definition of min/max values is required. Numbers are of type int32_t. If negative numbers are allowed within min - max, an additional button is displayed to switch the sign between + and -.

It is also possible to define a header text, as shown in this example app with the 3 different input options.
