           Summary: Clean up NAN in JavaScriptCore?
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Minor
          Priority: P3
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: darin at apple.com
                CC: sam at webkit.org, ggaren at apple.com


JavaScriptCore uses the following redundant ways to get the double NAN:

    function std::numeric_limits<double>::quiet_NaN()
    global KJS::NaN
    macro NAN

There's also code that says (isnan || isinf) where it could more efficiently
say !isfinite instead. We should clean this up. I'd like to see KJS::NaN and
KJS::Inf go away entirely.
