How do you access the atan2 function in Construct?

I notice that I can only access the "basic" trigo functions like sin, cos, tan, asin, acos, atan in Construct. But it doesn't recognise the expression when I write atan2.

Is there a smart/non-tedious way of implementing the atan2 function in Construct?

Thanks.

This can be used instead of atan2:
