Math.round() in Design Studio 1.4?

Hi,

I'm trying to round a large number using Math.round function within my script.

Unable to do so, I follow up some post on design studio sdk, where this function has been used.

Not sure if this is not supported by DS1.4, please advise, thanks

Error: Couldn't resolve reference to member Math.round

Please advise if there is a work around to this?

All i can think at this point is formatting the number in bex, thanks

Appreciate your response!!
