I'm working on a component for Joomla 3.2 which needs the user to input some data in the backend, so somebody before me coded a quite effective configuration form. Now I need to extend it, adding some fields which are required by my functionalities and a couple of the fields should be floats.
Joomla's standard form field type list doesn't list any "float" field type and number looks a lot like an integer field to me. There is a way to have number behave like a float or some obscure "float" form type hidden somwehere or should I code the new form type?
Use a float number on the "step" attribute.
Example:
<field
name="mynumbervalue"
type="number"
default="0"
label="Choose an number"
description=""
min="0"
max="10"
step="0.01" />
