Number
The number input type allows the user to select number from any mechanism
provided by the browser or to simply enter a numerical value if only a standard input
field is provided by the browser. The value is validated by the browser to ensure that
a number is indeed entered by the user. In mobile devices, where a digital keyboard
is provided for data entry, this input type hints to the system that the keyboard to be
provided should be the most appropriate for entering numbers.
