If I have some view say page.scala.html and I passed a hash map to this view. Now I want to extract and perform some arithmetic operations on this page like this:

    @pageMap.get("newPt") - @pageMap.get("oldPt") = 
(((@pageMap.get("oldPt")) - (@pageMap.get("newPt")))

but instead of printing the diff on right side I got the values of "oldPt" and "newPt" something like this:

50 – 40 = (((50)) – ((40)))

How to overcome this problem?

Answer 1

You can write blocks of scala codes using the @( … ) or @{ … } syntax.

@pageMap.get("newPt") - @pageMap.get("oldPt") = @{pageMap.get("oldPt") - pageMap.get("newPt")}
