how to use functions in javascript?

[nitin2003]

I am using 'Own Javascript' module and I need to use round function but it is giving me an error. It says variable round has not be defined.

How to use round function properly here?

e.g.
{-Variable.Variable2-}+ round(0.8*{-Variable.Variable4-})

Thanks

var x={-Variable.Variable2-}+ Math.round(0.8*{-Variable.Variable4-})
