Problem
By default display "1" not "1.0"
The user may believe that an integer value must be entered or it's a Double value
Proposed Solution
Show default value to "1.0"
Optional set a tooltip or place holder text for show plage range "0.0 to 1.0" value
The best now:
When user change value, it's value not in correct plage play a beep and reset value default "1.0"
