Summary: Strange results calculating a square root in a loop
Product: WebKit
Version: 528+ (Nightly build)
Platform: Macintosh
URL: http://jsfiddle.net/LgEDL/1/
OS/Version: Mac OS X 10.8
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: JavaScriptCore
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: konstantin.k.ed at gmail.com
I'm computing the square root of an arbitrary number about a 1000 times and printing the result only if it's less than 0. At some point it starts printing 2.236.... (for sqrt of 5) which is the expected result, but shouldn't be printed since it's not a negative number. Furthermore, some iterations later it starts printing some large (negative for some inputs to sqrt) number.
I noticed it breaks for some numbers inside sqrt (5,7,11,15) but not for others (6, 13)
