min(set) 
Operator Type:  Set maths 
Operator Scope of Action:  Set 
The min() operator returns the largest item in a set.
Both the operators max() and min() use lexical comparison in most cases, but numeric comparison if the context is numeric, e.g.:
Width=min("100;2;70")
Since "Width" is numeric, min() will be return 2.
Name=min("100;2;70")
Since "Name" is a string, mix() will return 100.
If you don't have a set, create one on the fly:
MyMin = min(collect_if(all,$MyNum>0,$MyNum))
A 'lexical sort' is a caseinsensitive sort (Aardvark,aarvark,ABLE) and for numbers "2;70;100;" would sort in order "100;2;70" (i.e. ordered on first number first  a number 'computer sort' )
