Specification of math expressions #579

Closed dweindl closed 1 week ago

dweindl commented 1 month ago

Previously, the math expression syntax wasn't specified. This was very problematic, because different libraries and programming languages have different names for the same functions, and more importantly, differ in operator precedence.

I'm happy with the proposed description. If anything I'd rename the false_value in piecewise to otherwise. But that wont do much in the end.
