           Summary: LLint: Number.MIN_VALUE is 0
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
               URL: http://jsfiddle.net/Gz9QC/
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dominic.szablewski at gmail.com


At least I suspect it's an issue with LLint: The JSFiddle test case work correctly in Mobile Safari on iOS6 (which uses the JIT), but fails in Chrome for iOS (which isn't allowed to use the JIT and thus falls back to LLint). 

A standalone version of libJavaScriptCore for iOS ( https://github.com/phoboslab/JavaScriptCore-iOS ) also has this problem on real hardware (again, using LLint), but works fine in the iPhone Simulator (using the classic interpreter).

Number.MIN_VALUE is defined as 5E-324, but the smallest representable number with LLint seems to be somewhere in the 5E-308 range - console.log(5E-309) shows 0 again.

An easy workaround would be to allow us to use the JIT on iOS ;-)
