which SQL datatype for values like "1.3" "3.5" ?

[carsten888]

I need to store values in a db table like:
1.3
3.7
4.6
etc.
when I try datatype tinyint the values loose their dot and the number behind it. With tinytext it works, but I realy need it to be numbers so 4,5
becomes
4.5
(notice the comma becomes dot)
its data which will have to be a bar chart in the front end, so no letters. when I try getting the post-values with intval($_POST['thing']); it returns nothing.

it is usually called a "double". Sometimes called "float"
