The following functions are available by default within any AMF model. AMF maps functions from Java static methods to any function, and we make use of common Java APId for this. The numeric operators use Math.java and their descriptions are from the Javadoc, Copyright 2004 Sun Microsystems, Inc. Author: Joseph D. Darcy. We need to add descriptions for most of the other functions and we'll have more functions available with Acore.
