Does play 2.0 template engine support the simple calculation in the html page.
Let us say, I create a sum.scala.html page:
@(a:String, b: String)
<html>
<head></head>
<body>
<h1> answer is getSum(@a,@b) </h1>
</body>
</html>
Is there any way that we could "getSum of a and b" via some function? or Does any play 2.0 expert know any good idea about calculation in play 2.0 template engine? Thanks

Have you tried @(a.toInt + b.toInt)?

You can just pass the value to template, can't you ?
@(a:String, b: String, c: String)
<h1> answer for @a + @b is @c </h1>
You can also call function from Yourcontroller in the template:
@Yourcontroller.getSum(a,b);
In /app/controllers/Yourcontroller.java ad the function (simplest sample):
public static Integer getSum(String a, String b){
Integer c = Integer.valueOf(a) + Integer.valueOf(b);
return c;
}
