How to put millisecond?

Example: I have text box called "cooldown" , to subtract five seconds , it appears that way:

5

4

3

2

1

You want to appear that way:

5.0

4.9

4.8

...

0.5 ...

Thank you =D

create variable with initial value 5

every 0.1 seconds --> subtract 0.1 from variable and set text to variable

variable < 0 --> set variable 0

create variable with initial value 5

every 0.1 seconds --> subtract 0.1 from variable and set text to variable

variable < 0 --> set variable 0

it works partially, but when it comes to an integer is so:

1 2 3 4 5

I would like to stay so:

0.0 1.0 2.0 3.0 4.0 5.0

I think zeropad(variable,1) will help you.

You can call into JavaScript.

Thank you for your help, zeropad it's the JavaScript worked perfectly =D
