[erlang-questions] How to define non_neg_float() type specification?

[Stavros Aronis]

Hello!

Unfortunately Dialyzer does not support it (even constants are generalized 
to any float, typwise). Consequentially, the type language does tnot 
support it. 
You can maybe try:

-type define non_neg_float() :: float().

This will help you documentation-wise and also (though in a somewhat 
limited way) Dialyzer-wise. If you use this type PropEr-wise however, you 
will get positive values, which you will need to filter...
