Using basic math functions in AF3 is problem:
- They need to be defined in the data dictionary
- When generating code however, "abs" and similar collide with the c definitions of these functions.
- Math functions build in and always available in AF3.
Workaround (low hanging fruit):
- In the generated code, all functions form the data dictionary get a pre- or suffixes as: "af3_fun_abs". This would avoid clashes.
