input field: slider - output/display is automatically rounding numbers

I’ve followed the guides in the CorvidReference on the step options for the slider input fields, and have the slider set up using the following values:

$w( " #slider1 " ).max = 4.00
$w( " #slider1 " ).min = - 8.00
$w( " #slider1 " ).step = 0.25
$w( " #slider1 " ).stepType = “value”

My issue is the display is rounding the output to .2 and .8, and I need it to display the actual step value of .25 increments, including .00 for the whole steps. How do I force it to display to 2 decimal points?
