Inverse tangent function in Dynare ++

Dynare help (legacy posts)

I am solving a model which includes the inverse tangent of a variable. While the code runs smoothly in dynare, it fails to do so in dynare++ .
The equation includes a term: atan(x) where atan is the inverse tangent. Do you know what the appropriate function in dynare++ is? Dynare++ returns a message like “unknown object atan”

Thanks,

Dynare++ does not support inverse tangent.
