Why do these two strings equal each other? 3

[KevinFSI]

<cfset varA = "018-009">
<cfset varB = "009-018">

<cfif varA IS varB>true<cfelse>false</cfif>

The above resolves to true.

however, <cfif Evaluate(varA) IS Evaluate(varB)>true<cfelse>false</cfif>

produces false

From what I can tell, the strings are being converted to dates. Both are interpreted as September 18 2013, which is why the comparison resolves to true. If you want to ensure a string comparison, use compare() or compareNoCase() instead.

Yeah, evaluate() converts those strings to numbers, ie +9 and -9, rather than dates. Cute, huh?
