Divide By Zero in Helix (Clarification)  
Introduction 
As with rounding, Helix uses two different rules when dividing by zero, depending on whether the values being used are Number ◊ or Fixed Point ◊ data type. This technote documents how Helix handles divide by zero for each data type. 

Divide By Zero: Scientific Result (Numbers) 
Number data (technically, floating point numbers) were introduced in the very first version of Helix and have always used scientific methodologies. In this case, the result of a divide by zero operation is Infinite. 

Divide By Zero: Financial Result (Fixed Point) 
Fixed Point data (technically, integers) were introduced much later in Helix’s history and have always used the financial rounding method. In this case, the result of a divide by zero operation is Undefined.
