i have used the following in code...it not works...

    price.text = obj.Price.toPrecision((18,4));

.kindly give ur suggestions folks....

Take a look at the NumberFormatter. To follow your example, you would declare a NumberFormatter like so:

<mx:NumberFormatter
    id="myNumberFormatter"
    precision="4"/> 

or in Actionscript:

var myNumberFormatter:NumberFormatter = new NumberFormatter;
myNumberFormatter.precision = 4;

Then use the NumberFormatter's format function on your value:

price.text = myNumberFormatter.format(obj.Price);
