No, it's behaving correctly, you've just found one of the edge cases with a loosely typed language. That second expression is equivalent to this one:
(i GT 0) LT 4 the "i GT 0" part evaluates to true. It's then used in a numeric context, so it is coerced to the numeric version of true, which is one. The result is compared with 4 using the LT operator, and since one is less than four, the result of the entire expression is true (or yes). These types of edge cases are what make loosely typed languages so dangerous and difficult to debug. As you saw, that second expression is happily evaluated, even though there's an extremely good chance that it's a typo and consequently a bug. With a strongly typed language, the compiler would catch the error for you. cheers, barneyb On Wed, 10 Nov 2004 23:56:21 +0000, Andy Jarrett <[EMAIL PROTECTED]> wrote: > Came across a weird one (or so i think) > > <cfset i = 5> > <cfoutput>#i GT 0 AND i LT 4#</cfoutput> > Returns NO - expected > > <cfset i = 5> > <cfoutput>#i GT 0 LT 4#</cfoutput> > Return Yes - not expected > > With the second snippet surely this should error?? > > Andy > www.andyjarrett.co.uk > -- Barney Boisvert [EMAIL PROTECTED] 360.319.6145 http://www.barneyb.com/blog/ I currently have 0 GMail invites for the taking ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Special thanks to the CF Community Suite Gold Sponsor - CFHosting.net http://www.cfhosting.net Message: http://www.houseoffusion.com/lists.cfm/link=i:4:183930 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
