How to use max() and min() functions

Hello,

Are any of the max or min functions implemented yet? The attribute evaluates to None in this case:

private import NumericalFunctions::max;
attribute value = max(1,2);

Same goes for ScalarFunctions::max and RealFunctions::max. Is there one that is implemented yet? Or is it that I am calling it incorrectly?

These functions are not yet implemented, please also see Advanced Technical Guide for what is. We will have more functions implemented in a future release.
