Posting JavaScript questions in the Java TA is not appropriate, and might make your question less likely to be answered. http://technojeeves.com/joomla/index.php/free/127-javascript-is-not-java

Please post the SSCCE so we can copy and paste the code into a script on our own servers.  Then we can see the exact failure you're seeing and we can discuss the reasons and solutions.

Please use the Code Snippet feature.  Thanks.

You're not limited to one set of {literal}{/literal}
So you can do :
<script type="text/javascript">
{literal}
        function emi()
        {
                var P = {/literal}$smarty.capture.$clean_price{literal}; // pick the form input value..
                var rate = 14; // pick the form input value..
                var n = 12; // pick the form input value..
                var r = rate/(12*100); // to calculate rate percentage..
                var prate = (P * r * Math.pow((1+r),n))/(Math.pow((1+r),n)-1); // to calculate compound interest..
                var emi = Math.ceil(prate * 100) / 100; // to parse emi amount..
        // to assign value in field1 as fixed upto two decimal..
                var finalemi= emi.toFixed();
                
        //to assign value in field2..   
                var tot = Math.round(document.formval.field1.value * n * 100)/100; // to calculate total amount
                document.formval.field2.value = Math.abs(tot);
        // to assign value in field3..  
                var int_amt = document.formval.field2.value - P; // to calculate net interest amount
                document.formval.field3.value =  int_amt.toFixed(2);
        } 
         
{/literal}
</script> 
<a href="javascript:void();" onclick="javascript:emi()" title="Emi From"></a>
