Detailed Description

Float type form element.

This is preferred over the text element when working with float numbers, and takes care of the fact that different languages may use different symbols as the decimal separator. Using this element, submitted float numbers will be automatically translated from the localised format into the computer format, and vice versa when they are being displayed.
