    Thanks Rupert

     

    I did find this:

    (<math equation>).toDouble().round(3)

     

    Still a rookie in the scripting work - not understanding the "Double" term.

     

    Thanks again...

Hi Rob,

 

No problem, happy to help :-)

 

In terms of the need for casting to Double, the reason I did that is because when you do:

 

def result=2.5064267352

 

This stores result as a BigDecimal by default. The cast to Double provides that class's round method.

 

Now BigDecimals can be rounded, but not using that simple 'round' method, which I thought you'd prefer, as its easier to get used to. 

 

Hope that helps,

Cheers,

Rupert
