Value should always be constrained to valid step values

Firefox 3.06, Windows XP 32Bit

Most of the time the slider value will return an integer, on occasional use, especially around the 2 mark, the code will break and return 1.99999998.

This screws up using a jquery wildcard to change the values of divs to show and hide elements. The change event code should hide all non relevant divs and then show() the correct one. I've left debug code in there to output the slider value to console.

I would imagine that the value function probably needs to be run through parseInt() before returning?

Snippet to reproduce:

Watch javascript console for occasional return of 1.99999998

<script language="JavaScript" type="text/JavaScript">

$(document).ready(function() {

$("#sliderdesc-<%=slider%>").show();

$("#slider").slider({

value:<%=slider%>,

min: 1,

max: 5,

step: 1,

change: function(event, ui) {

$("div[id*='sliderdesc-']").css("display", "none").filter("#sliderdesc-" + $("#slider").slider("value")).show();

console.info($("#slider").slider("value"));

}

});
