https://bugs.webkit.org/show_bug.cgi?id=46990

           Summary: TypedArray - NaNs converted to 0 in Float32 array
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebGL
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: josh at lindenlab.com


var n = 1 / "abc";
>> NaN

new Float32Array([n])[0];
>> 0, expecting NaN

Other edge cases (positive/negative infinities, negative zero) behave correctly:

new Float32Array([1/0])[0];
>> Infinity

new Float32Array([-1/0])[0];
>> -Infinity

var negzero = -0;
function isnegzero(x) { return 1/x == -Infinity; }
isnegzero(new Float32Array([negzero])[0]);
>> true
